Lack Of Penis Bone In Humans Linked To Monogamous Relationships, Quick Sex

Scientists reveal why humans do not have a penis bone.

By

Many of us call erections “boners,” although there’s no actual bone in the penis. This bone has been the subject of many debates as several animals have them in diverse sizes and lengths, but humans don’t. Evolutionary scientists at the University College London suggest this strange anomaly is a consequence of monogamy and quick sex.

The penis bone, also known as the “baculum,” evolved in mammals more than 95 million years ago, and was spotted in the first primates that emerged about 50 million years ago, according to the researchers. The baculum became larger in some animals and smaller in others. For example, in the walrus, it can be two feet long, while in a monkey it’s about the length of a human fingernail.

Previous research has found the penis bone increases the potential duration of intercourse, and the frequency with which sex can take place. A lioness can copulate 100 times per day, sometimes with only four-minute intervals, but has just a 38 percent conception rate. This means males need to have better sexual stamina to achieve the best chance of paternity.

So, why do humans lack a penis bone?

The recent study, published in Proceedings of the Royal Society, found a link between penis bone length, promiscuity, and sex duration. Some species have longer penis bones because they engage in “prolonged intromission,” which means the act of penetration lasts for more than three minutes. Longer intromission times are more common among polygamous mating species, where multiple males mate with multiple females, like bonobos and chimps. This mating system creates an intense competition for fertilization, and reduces a female’s access to more mates by having males spend more time having sex with them, according to the study.

The penis bone is attached at the tip of the penis rather than the base to provide structural support for animals who do prolonged intromission, and to keep the urethra open.

The researchers believe humans lost their penis bones when monogamy became a dominant reproductive strategy about 1.9 million years ago.

“We think that is when the human baculum would have disappeared because the mating system changed at that point,” Kit Opie, a co-author of the study at University College London, told The Guardian.

Opie and his colleague Miranda Brindle believe the male does not need to spend a long time penetrating the female since she is not likely to be leapt by other amorous males. Therefore, the reduction of competition for mates means humans are less likely to need a penis bone. Opie adds, despite popular belief, humans do not generally need longer than three minutes to get the job done, and successfully impregnate a woman.

“We are actually one of the species that comes in below the three minute cut-off where these things come in handy,” he said.

Scientists have just begun to put together the function of this mysterious bone. They do agree changes in the penis bone are driven as part of a mating strategy. This means a bigger penis bone is better when it comes to sexual competition.

Human males, do not feel bad — if the penis bone is damaged, it could take as long as other broken bones to heal.

Hard times – the ups and downs of the penis

Penises can be problematic. They are powerful, untameable beasts, capable of wielding immense pleasure but also able to cause devastating emotional wounds. And that’s just anal sex

fun, fun, fun

by Liam Murphy

As well as the obvious physical harm that can be inflicted – skinny jeans have cursed a generation to suffer cock-caught-in-fly related trauma – the magnificent meat mallet can also bring mental torment when, like an untrained puppy, it just won’t do as it’s told.

THE HARDER THE BETTER?
Some of the best things are hard: hard-boiled eggs, biscuits, those rhubarb and custard sweets, Tom Hardy and, of course, the penis. However, sometimes they can spring up at the most unexpected and inopportune times, and just won’t go away.

“I call my hard-on issue uncontrollable as such,” says 21-year-old Ian, “let’s say ‘eager’ or ‘keen’. It doesn’t take much and it’s ‘up periscope’ time. I’ve been this way as long as I’ve appreciated the male form. I went through a phase of wearing an over the shoulder bag in my late teens so I could cover the odd bus boner (the vibrations cause a right disturbance). Rather that than poke someone in the eye on the way past, I guess!”

However, impromptu erections can also lead to embarrassing retail situations, as Ian explains. “Recent men’s fashion means that I’ve become accustomed to skinny fit jeans, and for whatever reason, I went commando that day – I’m sure you know where I’m going with this – and I guess it must have been particularly sensitive or whatever. Anyway, I ended up with a lob-on in Tesco. My skinny jeans/tight t-shirt combo meant there was no hiding, so I did what any self-respecting bloke would do. I awkwardly leant over the shopping trolley for the next ten minutes. On the upside, I can also get hard on demand! It’s just a combination of a high sex drive and an involuntary physical reaction, I think.”

For Kieran, 25, his perilously perky penis is just part of his day. “I wouldn’t say it’s an issue – more just a fact of life. Some people sweat a lot, some people yawn a lot… I get boners a lot. Not getting them would be an issue, but getting too many, yeah that’s a ‘problem’ I’m OK with – at least I know it’s all working well. It does pop up at any time. When I was due to be giving a talk, someone gave me a wink and boom… up popped my friend downstairs to take his moment centre stage. I stood behind the lectern desperately thinking of Margaret Thatcher and trying to kill it so I could step out and begin my talk properly. The worst though, is when someone you don’t fancy or don’t want to have sex with tries it on and it just feels like he’s betraying you.”

And how does one manage the curse (or blessing, depending on your perspective) of a perpetual hard-on? “Like everyone else I learned the ‘tuck it behind your belt’ trick, or to hide it behind my belt. Granted, occasionally there have been times when I’ve had to miss my tube stop and stay sitting down while I waited for one to subside.”

Will, 38, didn’t notice the problem cropping up until he was in a relationship. “I was never aware of it until I met my boyfriend and it became apparent early on that I would get erect whenever I was around him. It has settled down a bit now but whenever we kissed in public I would get a twinge. And in bed it still sometimes feels like I have an erection all night. I would generally be embarrassed that I was getting these erections. I felt immature. This is what happens to a teenager, not an adult. I was going through a difficult break-up once – lots of tears – we were cuddling and I was hard. I realised then that my hard-ons were not always about sex – to me they were about love too.”

PENIS PROBLEMS
Erectile dysfunction can happen to a lot of people, in varying degrees and for many reasons, medical or otherwise.

“It happens to me every time I put on a condom,” admits Steven, 34. “I have no problem keeping it up before fucking – wanking and getting sucked off have never been a problem – but when I go to fuck someone and I slide the condom on, I lose the hardness. Not totally, but enough that I can’t properly put it in someone’s arse and enough that the sensation goes for me.”

Steven tried mixing up condom brands. “I’ve used thin, ultra-thin, ribbed, tingle… every version of a condom you could imagine and I still get the same flaccid result. I think it must be a psychological thing, because it’s not like I can’t get hard at all. It’s fine when I bareback with long term boyfriends, but with one nighters I tend to have to bottom now.”

Anxiety can often be a cause of not being able to maintain an erection, as 27-year-old James confirms: “Sex in general makes me anxious. I hate getting naked and I get so nervous when it comes to getting down to it in bed. I was dating a guy I really liked, so much that when he touched me I would physically shake, but when it came to sex I just couldn’t get hard. He thought I didn’t like him! And now I dread having sex. I love the dating side of it but I always know that heading to the bedroom is going to be inevitable.”

What can cause you to have trouble getting or staying hard?

  • Stress and anxiety.
  • Depression.
  • Hormone levels.
  • Smoking, recreational drugs and alcohol.
  • Some prescribed drugs – like Prozac and Seroxat.
  • Diabetes, high cholesterol and high blood pressure.
  • Psychological reasons – the more you worry about your erection, the less likely you are to be able to get one.

What can I do to make myself hard?
If you think the reason is psychological – a distraction helps, so encourage your partner to focus on something other than your cock for a while – kissing or nipple play might help to get you back in action.

  • Cockrings can also be used to help maintain a hard-on – leather or rubber straps are safer to use.
  • Counselling.
  • Drugs like Viagra or Cialis – consult your doctor for these.

Matthew Hodson, CEO of GMFA told us: “Rolling a condom onto a rock-hard penis isn’t a problem but if it’s a bit soft and you start to get anxious then it’s easy to spiral with anxiety to the point where a condom is really tricky to use. The more you’re concerned that you won’t be hard enough to use a condom, the more likely it is to happen. If it’s just an occasional problem it’s probably best not to make a big thing of it and just do something else that turns you on while you wait for it to get hard again. If it’s becoming more of a problem, you might want to experiment with cock-rings or talk with your GP about it – there’s no need to be embarrassed, you won’t be the first person who will have approached them with the same problem. Most erection problems can be addressed so there’s no reason why a temporarily soft dick should be a long-term barrier to you enjoying sex safely.”

Everyone should be able to enjoy a penis (which is my campaign slogan if I ever run for Prime Minister), especially their own. Whether it’s too hard or too soft, it doesn’t mean you and your cock have to suffer alone. Confide in your partner/lover/friend/doctor and discuss what you can do to get you and your lifelong pleasure companion talking again.

Step 1: When your cock is hard, take the condom out of the wrapper carefully using your fingers. Using your teeth to tear the packet could damage the condom. Squeeze the air out of the teat on the tip of the condom (if there is one) and put it over the end of your cock. Don’t stretch it and then pull it over your cock as this will make it more likely to break.

Step 2: Roll it down the length of your cock – the further down it goes the less likely it is to slip off. Put some water-based or silicone-based lubricant over your condom-covered cock. Put plenty of lube around his arse too. Don’t put any lube on your cock before you put the condom on, as this can make it slip off.

Step 3: Check the condom occasionally while fucking to ensure it hasn’t come off or split. If you fuck for a long time you will need to keep adding more lube. When you pull out, hold on to the condom and your cock at the base, so that you don’t leave it behind. Pull out before your cock goes soft.

What lube should I use?

When you don’t use enough lube, or use the wrong kind, the likelihood of condom failure is increased, making transmission of HIV and other STIs possible. Water-based lubes (e.g. K-Y, Wet Stuff and ID Glide) and silicone-based lubes (Eros Bodyglide and Liquid Silk) work well with condoms. Oil-based lubricants like cooking oil, moisturisers, sun lotions, baby oil, butter, Crisco, Elbow Grease, etc. can also cause latex condoms to break.

They can however be used with non-latex condoms, like Durex Avanti, Mates Skyn or Pasante Unique. Don’t use spit as it dries up quickly and increases the chance of your condom tearing.

Why Can’t I Orgasm During Sex? Chronic Pain And 5 Other Factors That Affect Ability To Climax

By

Imagine this: You and your partner are getting hot and heavy in between the sheets. You’re feeling sexually aroused — but you’re unable to climax. In frustration you ask yourself: “Why can’t I orgasm during sex?”

The Kinsey Institute indicates 20 to 30 percent of women don’t have orgasms during intercourse, compared to only 5 percent of men who don’t climax every time they have sex. Men and women who are unable to sustain an erection or reach orgasm, respectively, are usually labeled as having some type of sexual dysfunction. However, the inability to orgasm could be triggered by several issues that range from physiological to psychological.

Below are six causes of why you have trouble orgasming during sex.

Tight Condoms

Condoms are often seen as an “evil” necessity that reduces sensitivity and sensations for men. The truth is condoms can inhibit male orgasm if they do not fit properly. A condom that is too tight can feel like the penis is in a chokehold, which can be distraction, and make it difficult to keep an erection. A 2015 study in journal Sexual Health found about 52 percent of men report losing an erection before, or while putting a condom on or after inserting into the vagina while wearing a condom.

Stress

High levels of stress impact your psychological and physiological health, which can interfere with the ability to orgasm. This makes it harder to concentrate on the sensation and relax during sex. Women with high salivary cortisol and stress levels have significantly less desire to masturbate or have sex with their partner.

Stress causes us to produce fewer sex hormones, like estrogen and testosterone, and more cortisol and stress hormones. When the body releases cortisol, a fight-or-flight response kicks in, and redirects the blood flow away from the sex organs, causing you to breathe shallowly.

Depression

Depression affects your mood, and even the desire to have sex. A 2000 study in the American Family Physician found 70 percent of adults facing depression without treatment had problems with their sex drive. This is because sexual desire starts in the brain as sex organs rely on chemicals in the brain to jumpstart your libido, and change blood flow. Depression disrupts these brain chemicals, making sexual activity more difficult to initiate and enjoy.

Chronic Pain

More than 75 million people live  with persistent or debilitating pain, according to the national pain foundation, which can often lead to a low sex drive. Chronic pain sufferers find it difficult to feel pleasure during sex since the body hurts all the time. This is unfortunate since having an orgasm can alleviate some pains and aches.

Prescription Meds

Drugs tend to be among the most common causes of sexual problems. Prescription meds are responsible for as many as one of every four cases of sexual dysfunction. A 2002 study published in Family Practice found statins and fibrates (used in lowering LDL “bad” cholesterol) may cause erectile dysfunction, while later research has found both men and women taking statins showed increased difficulty achieving orgasm. The levels of sexual pleasure declined along with LDL cholesterol.

Negative Body Image

When you feel good about your body, you tend to feel better psychologically as well. The mind-body connection is imperative in sexual pleasure. For example, if you feel bad about your body, it;ll become more difficult to enjoy sex and have orgasms. A 2009 study in The Journal of Sexual Medicine found women between the ages 18 to 49 who scored high on a body image scale were the most sexually satisfied. Positive feelings associated with weight, physical condition, sexual attractiveness, and thoughts about our body during sex help promote healthy sexual functioning.

Cancer patients and survivors can have trouble with intimacy

People who survive cancer treatment — a growing group now topping 5 million — often have trouble with intimacy afterward, both from the actual treatment and physical recovery and from the psychological damage of feeling so vulnerable.

In the mirror, Kelly Shanahan looks normal, even to herself.

Kelly Shanahan of South Lake Tahoe, Calif., has been battling breast cancer for eight years. She’s a big believer in doctors and their patients discussing sexual health.

But she does not feel like herself.

The breasts she had reconstructed eight years ago look real, the nipples convincing. But her breasts have no sensation. The only time she feels them at all is during the frigid winters of her South Lake Tahoe, Calif., home, when they get so cold, she has to put on an extra layer of clothing.

“For a lot of women, breast sensation is a huge part of sexual pleasure and foreplay. That is totally gone,” says Shanahan, 55, who has lived with advanced breast cancer for three years. “It can be a big blow to self-image, even though you may look normal.”

Shanahan is part of a growing group of patients, advocates and doctors raising concerns about sexual health during and after cancer treatment.

“None of us would be here if it weren’t for sex. I don’t understand why we have such a difficult time talking about it,” she says.

Though virtually all cancer diagnoses and treatments affect how patients feel and what they think about their bodies, sex remains an uncomfortable medical topic.

Shanahan, an obstetrician herself, says that until her current doctor, none of the specialists who treated her cancer discussed her sex life.

“My former oncologist would rather fall through the floor than talk about sex,” she says.

Major cancer centers now include centers addressing sexuality, but most community hospitals still do not. The topic rarely is discussed unless the patient is particularly bold or the doctor has made a special commitment.

There’s no question that cancer can dampen people’s sex lives.

Hormone deprivation, a common therapy for breast and prostate cancer, can destroy libido, interfere with erections, and make sex extremely painful. Weight gain or loss can affect how sexy people feel. Fatigue is unending during treatment. Body image can be transformed by surgeries and the idea that your own cells are trying to kill you. The constant specter of death is a sexual downer, as are the decidedly unsexy aspects of cancer care, like carrying around a colostomy bag. Then, there are the healthy partners, feeling guilty and terrified of causing pain.

And once people start to associate sex with pain, that can add apprehension and muscle tightness, which makes intercourse harder to achieve, says Andrea Milbourne, a gynecologist at the University of Texas MD Anderson Cancer Center in Houston.

There’s almost never a medical reason cancer patients or survivors shouldn’t be having sex, says Karen Syrjala, a clinical psychologist and co-director of the survivorship program at the Fred Hutchinson Cancer Research Center in Seattle. Even if there is reason to avoid intercourse, physical closeness and intimacy are possible, she says, noting that the sooner people address sexual issues the less serious those issues will be.

“Bodies need to be used and touched,” she says said. “Tissues need to be kept active.” Syrjala recommends hugging, romantic dinners, simple touching, “maybe just holding each other naked at night.”

There are ways to improve sexual problems, starting with doctors talking to their patients about sex. Milbourne and others say it’s their responsibility, not the patients’, to bring up the topic.

Hormone deprivation, a common therapy for breast and prostate cancer, can destroy libido, interfere with erections, and make sex extremely painful. Lubricants can help smooth the way.

Communication between partners also is essential. “A lot of times, it’s unclear, at least in the mind of the other partner who doesn’t have a cancer, what has happened. ‘Why does this hurt? Why don’t you want to do anything?’ ” Milbourne says.

For women who have pain during sex, Milbourne says one study found benefit to using lidocaine gel to numb vaginal tissue.

Jeanne Carter, head of the female sexual medicine and women’s health program at Memorial Sloan Kettering Cancer Center in New York City, recommends women do three minutes of Kegel exercises daily to strengthen their pelvic floor muscles and improve vaginal tone, and to help reconnect to their bodies.

For women sent abruptly into menopause, moisturizing creams can help soften tissue that has become brittle and taut. Carter says she’s conducted research showing that women with breast or endometrial cancers who use moisturizers three to five times a week in the vagina and on the vulva have fewer symptoms and less pain than those who don’t. Lubricants can help smooth the way, too.

“We’ve got to make sure we get the tissue quality and pain under control or that will just undermine the whole process,” Carter says.

Sex toys also take on a different meaning after cancer treatment. Specialized stores often can offer useful advice and the ability to examine a product before buying. Rings and other equipment, in addition to medications such as Viagra, can help men regain erections.

Doctors and well-meaning friends also need to stop telling cancer patients that they should simply be glad to be alive, Shanahan says. Of course she is, but eight years after her initial diagnosis and three years after her disease advanced, Shanahan wants to make good use of the time she has left.

And that, she says, includes having a warm, intimate relationship with her husband of 21 years.

Expert Shares Tips for Talking Sexual Health With Cancer Survivors

by KATIE KOSKO

prostatecancer_600x450

Sexual health can be an uncomfortable or embarrassing topic to discuss for many people, and for patients with cancer and survivors it can feel even more awkward. Nevertheless, sex ranks among the top 5 unmet needs of survivors, and the good news is, proactive oncology practitioners can help fill that void.

Sixty percent of cancer survivors—9.3 million individuals in the United States alone—end up with long-term sexual problems, but fewer than 20% get professional help, according to Leslie R. Schover, PhD, founder of the digital health startup, Will2Love. Among the barriers she cited are overburdened oncology clinics, poor insurance coverage for services related to sexual health, and an overall lack of expertise on the part of providers, many of whom don’t know how to talk to patients about these issues.

And, oncologists and oncology nurses are well-positioned to open up that line of communication.

“At least take one sentence to bring up the topic of sexuality with a new patient to find out if it is a concern for that person,” Schover explained in a recent interview with Oncology Nursing News. “Then have someone ready to do the follow-up that is needed,” and have other patient resources, such as handouts and useful websites, on hand.

Sexual issues can affect every stage of the cancer journey. Schover, who hosted a recent webinar for practitioners on the topic, has been a pioneer in developing treatment for cancer-related problems with sexuality or fertility. After decades of research and clinical practice, she has witnessed firsthand how little training is available in the area of sexual health for healthcare professionals.

“Sex remains a low priority, with very little time devoted to managing sexual problems even in specialty residencies,” said Schover. “I submitted a grant four times before I retired, to provide an online interprofessional training program to encourage oncology teams to do a far better job of assessing and managing sexual problems. I could not get it funded.”

In her webinar, she offered tips for healthcare practitioners who want to learn more about how to address sexual health concerns with their patients, like using simple words that patients will understand and asking open-ended questions in order to engage patients and give them room to expand on their sex life.

Schover suggests posing a question such as: “This treatment will affect your sex life. Tell me a little about your sex life now.”

Sexual side effects after cancer treatment vary from person to person, and also from treatment to treatment. Common side effects for men and women include difficulty reaching climax, pain during sexual intercourse, lower sexual desire and feelings of being less attractive. Men specifically can experience erectile dysfunction and dry orgasm, while women may have vaginal dryness and/or tightness, as well as loss of erotic sensation such as on their breasts following breast cancer treatment.

Sexual dysfunction after cancer can often lead to depression and poor quality of life for both patients and their partners.

According to Schover, oncologists and oncology nurses should provide realistic expectations to patients when they are in the treatment decision-making process.

“Men with prostate cancer are told they are likely to have an 80% chance of having erections good enough for sex after cancer treatment,” Schover says. “But the truth is it’s more like 20 to 25% of men who will have erections like they had at baseline.”

To get more comfortable talking about sex with patients, Schover advises role-playing exercises with colleagues, friends, and family—acting as the healthcare professional and then the patient. When the process is finished, ask for feedback.

Brochures, books, websites and handouts are also good to have on hand for immediate guidance when patient questions do arise. But Schover is hoping for a bigger change rooted in multidisciplinary care and better patient–provider communication to find personalized treatments tailored to each individual’s concerns and needs.

Cancer treatment can impact hormonal cycles, nerves directing blood flow to the genitals, and the pelvic circulatory system itself, she explained. In addition, side effects like prolonged nausea, fatigue, and chronic pain also can disrupt a patient’s sex life.

“Simply to give medical solutions rarely resolves the problems because a person or couple needs to make changes in the sexual relationship to accommodate changes in physical function,” Schover stressed. “That kind of treatment is usually best coming from a trained mental health professional, especially if the couple has issues with communication or conflict.”

Schover wants to make sure that those resources are easily accessible to patients and survivors. Thus, she has created the startup, Will2Love, which offers information on the latest research and treatment, hosts webinars, and provides access to personalized services.

“Sexual health is a right,” concluded Schover, and both oncology professionals and patients need to be assertive in getting the conversation started.
