Interesting facts about Penis

You can break your penis

There is no "penis bone" but you can break your penis. It's called penile fracture. When it happens, there's an audible pop or snap. Then the penis turns black and blue and there's terrible pain. Penile fracture is rare, and it typically happens to younger men because their erections tend to be quite rigid.

Here's how to avoid penile fracture: don't use your penis too roughly. A common way that penile fracture happens is when a man is thrusting too hard and fast during sex, and slams into his partner's pubic bone. Also, a woman who moves wildly while on top of a man during sex can break a man's penis.
Peyronie's syndrome is a related condition that tends to show up more in older men. An older man's erection may not be as rigid, but still is hard enough for sex. Over time, if the penis bends too much a certain way during sex, small tears in the tissue can form scars, and the accumulated scar tissue gives the penis an abnormally curved shape.
