No matter how open you are with your boyfriend, there are some things even the gutsiest gals are too shy to ask. Get the answers to all the questions you always wanted to ask your man, and a few answers to questions you never even thought of!
1. Only 6 percent of the male population needs extra-large rubbers, according to condom manufacturers. In other words, 94 percent of men lie.
2. The study most trusted by urologists shows that the average erect penis size is 5.1 inches long and 4.8 inches in girth. Unless you're in a chat room. Then double it.
3. About 80 percent of American men are circumcised, even though the American Academy of Pediatrics says it's not medically necessary. No word on why men insist on cutting something they're always exaggerating about.
4. Men really do get "blue-balls." Technically called "prostatic congestion," the achiness in the testicles is caused by "trapped" blood. You know that crap he lays on you about orgasms being the only way to relieve it? He's right. But not so fast, trampolina. So is your doctor
5. Penises are generally darker in color than the bodies they hang from. Why? It's part of the sexual maturation process, but it's also because during puberty nature introduces men to a special friend: their right hand. As Mr. Nice to Meet You Too, You Can Let Go Now will tell anybody who'll listen, your skin would darken too if you were manhandled that often.
6. There is no correlation between penis size and shoe size, hand size or nose size. And the bad news is even worse for gold-digging nymphos: There's no correlation between penis size and wallet size.
7. Masturbation, or "punching the monkey," is healthy. No, really. "Use it or lose it" isn't just an excuse for a guy's hands to migrate south; it's the official tested and studied conclusion of sex experts. The less a guy uses his sexual plumbing, the more problems he'll have pumping the well later on. It's only at Thanksgiving that you should tell your man, "Don't play with your meat."
8. Men will go limp if they drink too much. But how much is too much? About three and a half drinks for a 150-pound man. After that, the only thing standing upright in your house will be the vacuum cleaner.
9. All men have a line going down their penis and over their testicles. And no, it's not the chow line. It's more a "seam" on the underside of the penis. It forms when the fetus is in the uterus. In women, the seam becomes the inner lips of the vagina. In men, the seam encloses the urethra along the length of the penis.
10. Nothing can make a penis bigger
