There is a correlation between infidelity and the size of a male’s testicles, researchers have found.

A study by scientists at the University of Oslo found that primates with bigger testicles were more likely to be unfaithful.

Petter Bøckman, Assistant Professor, said: “We can determine the degree of fidelity in the female by looking at the size of the male’s testicles. The less faithful the female, the larger the male’s testicles.

“If the male will only fertilise one female and has no competitors, he only needs sufficient sperm to reach the egg. If the female mates on the side, it is smart to have as many cars as possible in the race.

“Then, the male must have testicles that are as large as possible.”

Prof Bøckman said bonobos have particularly large testicles and mate in large groups whereas gorillas have small testicles.

He said: “There is an abundant flow of semen. Those who leave the greatest amount of sperm have the largest chance of fathering offspring.

“In gorilla troops there is only one male. Even though the gorilla has a small harem, he has no need for large testicles – his balls are tiny.”

Large testicles can increase the risk of testicular cancer, the study found.

“Animals with short lifespans may have enormously large testicles. In one type of grasshopper the testicles occupy half their body mass,” said Prof Bøckman

“The testicles are even larger in sea urchins. They spawn directly into the ocean. To increase the chance of fertilising an egg, the sea urchin is a huge testicle with a little shell around it.”

The testicles of humans are one and a half times larger than those of gorillas.

Prof Bøckman said: “This testifies with abundant clarity to life in our flock. We can pledge our fidelity until we are blue in the face, but this is evidence that our females are cheating.

“We are not like chimpanzees, where the female has four or five sexual partners every time she is in heat, but there is always a certain likelihood that the neighbouring male has dropped by.”

The testicles are also large in animals that have sex with many females.

Prof Bøckman said: “Male lions have huge balls. All the females in the pride must have sex at the same time. When the female lions in the pride are in heat, he must mate with all the females every half-hour for three days.”

Your Cock; A Complete Owners Manual (abridged)

Name: Hector
Gender: male
Age: 17
Location: Tujunga, CA
I’m afraid my penis isn’t right. I worry because it doesn’t look like other guys. For one thing I’m a lot smaller. I’m afraid to have sex or show my penis. Is there any way for me to know for sure? I hope to hear from you because this is making me real nervous. Thank you.

first-life-form-with-a-penis-humor

I’d chill out, if I were you, Hector. Lots of guys your age mistakenly think there is something wrong with their unit, when actually their willie is quite normal. This heightened concern, as you suggest, can lead to anxiety or even a complex about one’s cock size and shape. You don’t really give me much to go on as to why you think your pinga is not like the other guys. That leads me to think you don’t really know all that much about your package in general. Do you? I mean, who are you comparing yourself to anyway?

Since I don’t have a lot of information to go on, I suppose we oughta start with some essentials. Here’s Part 1 of my primer — Your Cock; A Complete Owners Manual (abridged). That’s supposed to be funny, BTW.

We all know that there are big ones and little ones, fat ones and skinny ones. Some are bobbed; some are whole. Some curve and bend; some are straight as an arrow. Some have a mushroom cap; some sport more of a helmet look. Some grow; some show. And they come in a veritable rainbow of colors.

Despite the amazing diversity, there are lots of things that each of our members has in common with everyone else’s. The average length of a flaccid cock is 3.7 inches with a diameter of 1.25 inches. The average length of a hardon is 5.1 inches, with a diameter of 1.6 inches. If you are over the age of 17, you pretty much have all the cock you’re gonna have. That’s not to say that as we age and as our muscles slack, our pal won’t hang a bit differently than when we were a young buck. But there’s not gonna be significant change in length or girth after puberty is done with us. Keep in mind that all this stuff is determined by genetics and heredity, like your overall body type, the color of your eyes, your hair pattern, and how tall you are. So the likelihood that any guy will add even one permanent inch to his dick either in length or girth, without surgery, is about as likely as him adding even an inch to his height.

The head of your dick is called the glans. (It’s the thing that can be shaped like a mushroom or a helmet.) It is made up of soft tissue called the corpus spongiosum. Just below the glans, on the underside of your cock is a waddle of skin called the frenulum. This puppy is chock-full of nerve endings that make it ground zero for dick-centered pleasure.

Male_anatomy

All uncut (uncircumcised) men have a prepuce, or foreskin that covers and protects his dickhead. Cut (circumcised) men don’t, because it has been surgically removed. If you are lucky enough to be intact, your foreskin is a highly specialized, sensitive, and functional organ of touch. No other part of the body serves the same purpose. Please note: circumcision actually removes 50% of the skin of a guy’s dick.  And who among us would choose that if we were allowed to choose?

You know the old adage, “Use it or lose it”? They may have had a penis in mind when that maxim was coined. Researchers agree — erections are good for you. When you get a woody, your cock is engorged with oxygen-rich blood, which is essential for the upkeep of the smooth muscle tissue. This kind of tissue makes up about 90% of your cock. You can see how a healthy circulatory system is vital to a vibrant sex life. An oxygen-deprived cock will build up a kind of plaque in your cock, which resembles scar tissue. This will cripple your rod (Peyronie’s disease) or rob you of your wood altogether.

penis mesureI also want to alert you of some startling new data that came out of recent research about masturbation. Australian researchers questioned over 1,000 men who had developed prostate cancer and 1,250 men who had not, about their sexual habits. They found those who had ejaculated the most between the ages of 20 and 50 were the least likely to develop prostate cancer.

The protective effect was greatest while the men were in their 20s. And get this; men who ejaculated more than five times a week were a third less likely to develop prostate cancer later in life. But let’s not get off topic too much.

The other big part of your package is the family jewels. We mind as well take a look at them too while we’re at it. Your nuts (testis) and the sack (scrotum) they’re housed in are an evolutionary marvel. Your testicles are about 4°F cooler than your core body temperature. Lucky for us, this is the ideal climate for healthy sperm production. 90% of the male hormone, testosterone, is manufactured in our balls. Evolution has even provided that one nut, generally the left, hangs slightly lower than the other. The lower nut will also be slightly larger. I suppose this keep them from knocking into each other so much.

Ok so you think the outside of your junk is pretty impressive, well you ain’t seen nothin’ yet! Here’s where things get really interesting. First, there is no “bone” in your boner. Don’t laugh! Humans are one of the few mammals (horses, donkeys, rhinoceros, marsupials, rabbits, whales and dolphins, elephants and hyenas are the others) that don’t have a penis bone. Most males of our species have a unique bone called baculum in their penis. The baculum is designed for speed fucking. Sliding a bone in and out of a sheath is much faster than waiting for hydraulics to kick in. This enables our mammalian relatives to spend very little time actually mating. Which is, after all, a vulnerable position for them to be in.happy penis

If there’s no bone in there what make our dick hard? Good question. If you dissected your woody and looked at a cross-section you’d see three distinct spongy tubular structures, each are made up of smooth muscle tissue. Two of these tubular structures — one on either side of your cock, both of which run the length of your cock — are called the corpora cavernosa. These marvelous structures become engorged with blood lifting and thickening your cock to erection. The corpus spongiosum, the third tubular structure is located just below the corpora cavernosa. This baby houses your urethra, through which urine and semen pass during urination and ejaculation, respectively. This may also become slightly engorged with blood, but less so than the corpora cavernosa.

There are several points of interest in and around your balls too. I already mentioned your urethra, which stretches from your bladder to the tip of your dick. It carries your piss and cum, but not at the same time, I’m happy to report. Your prostate is an almond shaped gland that sits between your bladder and the root of your dick. Slightly in back of that is a pair of glands called the seminal vesicles. These tubular glands open into the vas deferens as it enters the prostate gland. They secrete the lion’s share of your spooge (ejaculate) about 70% to be precise. Most of us have two vas deferens tubes to correspond to the pair of ball (testicles) most of us have. These convey your mature sperm, the ones that have been comfortably relaxing in the epididymis, which is a tube filled mass at the back of each of your balls.

To conclude, the average male, between the ages of 15 and 60 will ejaculate 30 to 50 quarts of jizz (semen), containing 350 to 500 billion sperm cells. How amazing is that?

Good luck

Is this gonna warp me?

Name: Jake
Gender: male
Age: 23
Location: Omaha
I’m 23, and I’ve been dating 30-year-old chick for nearly a year now. I come from a very conservative Christian upbringing and I love that she is more experienced than me. My girlfriend likes to tie me up. I’m a college gymnast so I have very defined muscles. They are a huge turn on for my girlfriend, which I guess explains why she likes to see me struggle against the rope. I get real turned on too when I’m tied up. Sometimes she teases my penis and testicles with a feather or a piece of leather, which drives me wild. I’m worried though, because I think this is gonna warp me somehow. Do you think this is perverted? Why is it so much fun?

Ahhh yeah Jake, I do think it’s perverted. I think your girlfriend is a big fat pervert and I think you’re still a little tiny pervert, but well on your way to being a big fat pervert, just like your girlfriend. So YAY for that!

bondage236And why is this bondage thing so much fun? It’s such a blast because it’s perverted, nasty and forbidden, silly! One can only guess what your fundamentalist Christian mom and dad would think about their star athlete son trussed up like a thanksgiving turkey while a considerably older dominatrix punishes his family jewels. I fear this apple has fallen a great distance from the tree, right Jake? I absolutely love it!

Bondage is fun for you because you have to relinquish all your male privileged, Christian, preppy frat boy control to this unlikely kinky lady friend of yours. And what’s even better, you let her have her way with you. I have a feeling you’re not telling us everything about what she does to you when you’re all tied up. I’d be willing to guess there is a lot more perversion here than meets the eye. Not that that’s a bad thing, necessarily. I think it can be very therapeutic as well as amazingly hot to be completely helpless and in the control of another.

For a dominatrix, like your girlfriend, there is, as you say, the visual aspect to bondage. I think she’d agree, there’s nothing sexier then young masculine, muscular male flesh wrapped in ropes while having his cock and balls available for discipline. It’s the ultimate form of objectification. And, I might add, that you guys are turning all of society’s conventions — particularly the sacred “male as top” thing — on their head. YOU GO!

This has got to turn your crank, on some base psychological level too. I would so love to know how you and your girlfriend met. How she introduced you to all this pervy stuff. And more importantly, how you came to submit so unequivocally. That’s the real story here.bondage237

Jake, you are on the cutting edge. I think you have some sense as to how radical your play really is, don’t you? And I think it’s the radical nature of your play that gives you pause, right? It’s not the actual bondage, discipline, and possible humiliation that concerns you as much as you feel like you are losing your moral moorings. Nothing about what you are currently experiencing at the hand of this woman has any connection to the life you were brought up in. That has to be a bit of a jolt, which makes it all the more enticing. And there is virtually no turning back, is there? Once you’ve tasted the sweetness of surrender, vanilla will never again be enough.

Trust me, none of this makes you a bad person. On the contrary, if you embrace and integrate all this new information about yourself and live your life with authenticity and integrity, it will make you exemplary.

I do have one fear, however. I fear that one-day you will begin to second guess your harmless submissive eroticism and cave to the dictates of the popular culture. The worst case scenario would be for you to continue to enjoy your BDSM lifestyle on Saturday nights, then rush off to church on Sunday morning to join the choir of sanctimonious hypocrites who do one thing in private, but who publicly endorse and promote a sex-negative message of repression and denial. That, my friend, would be criminal…and a real perversion.

Good luck

8 Steps for Choosing a Strap-On Harness for Men

By Mistress Kay

Strap-on fun isn’t just for women. Men can have fun, too. Use these 8 steps to choose the best strap-on harness for your needs.

Deuce02

Did you know that even if you have a penis that you can still wear a strap-on harness? Yes, manufacturers make strap-on harnesses for the male-bodied as well as the female-bodied. While males can definitely wear strap-on harnesses designed for women, some find that the pressure it places on the penis and testicles to be uncomfortable. Strap-on harnesses for male bodies are designed with a penis in mind, providing much better comfort.

Strap-ons for people who have a penis can be used for a variety of play times. Some people like to use them as an alternative to penetrative sex (or in kinky contexts, as a “punishment” where the wearer doesn’t get to be directly involved in stimulation). Other people like to strap them on to continue the penetrative action after the penis has gotten soft (due to orgasm or other reasons). Yet others like to explore the idea of double penetration.

What Makes These Dominican Children Grow Penises at Puberty?

By Michele Debczak

guevedoces

In the Dominican Republic, the phenomenon of children who were raised female appearing to swap sexes at puberty is so common it even has a name. Guevedoces roughly translates to “penis [or “balls”] at 12,” and it’s the result of a rare enzyme deficiency that delays crucial steps of male sexual development until puberty.

When guevedoces are born, they appear to have external female genitalia even though their genes and internal reproductive organs are male. Parents assume their children are girls and raise them as such. But when these children begin producing large amounts of testosterone at puberty, their testes descend and they grow a penis—in addition to all the other changes that come along with male adolescence. 

Sexual development normally begins in the womb, and the same is true for guevedoces. Whether the fetus has one X chromosome or two, for the first several weeks of development its genes follow the same blueprint for both sexes. Then, sometime around the eight-week mark, the sex chromosomes get to work. For males, the undeveloped gonads become testicles and they start to release male hormones, including testosterone. In a structure called the tubercle, an enzyme called 5-alpha-reductase converts the testosterone to a stronger hormone called dihydrotestosterone (DHT), which is necessary to develop external genitalia. It’s this hormone that turns the tubercle into a penis; without it, it develops into a clitoris.

The rare enzyme deficiency found in guevedoces leaves them unable to develop external male genitalia in the womb. They still produce plenty of testosterone, which triggers the development of internal structures like the epididymis and vas deferens, but the lack of DHT makes the babies appear female at birth. It’s not until the second surge of testosterone these children receive at puberty that they grow testes and a penis.

The condition is thought to be genetic, tracing back to the female founder of a small village in the Dominican Republic’s mountainous hinterland. Outside of the nation, it’s incredibly rare.

For some guevedoces, being raised as female wasn’t an easy experience. “I never liked to dress as a girl, and when they bought me toys for girls, I never bothered playing with them,” Johnny, who had grown up as Felicita, told BBC Two, which features these kids in the second episode of the series Countdown to Life: The Extraordinary Making of You. “When I saw a group of boys, I would stop to play ball with them.” When Johnny, now 24, began to undergo physical changes, he was taunted at school and called nasty names by his classmates. He’s had a number of short-term girlfriends since going through puberty and dreams of one day getting married and starting a family. Another child named Carla began the process of transitioning to Carlos at age 9; he can be seen receiving a smile-inducing haircut in the photo above.

Most people with this condition live out their adult lives as men, but some choose to undergo surgery and remain female. The discovery of this disorder in the 1970s led to the development of a best-selling drug called finasteride, which is commonly prescribed to treat benign enlargement of the prostate and male pattern baldness. (You may know it by the brand name Propecia.) The drug mimics the enzyme deficiency by blocking the action of 5-alpha-reductase.

You can learn more about this rare condition and the people who have it on the BBC Two series Countdown to Life: The Extraordinary Making of You.
