It's the world's oldest question. No, not "to be or not to be," but "does size matter?"
A guy who didn't get a true education about sex from his parents or teachers -- locker room jokes don't replace real knowledge -- usually comes to the conclusion that the size of his penis matters a great deal and he, pun intended, comes up short. Nothing is more embarrassing for a guy than the false knowledge that he's inadequate in any sexual way.
Truth is, an extremely large unit will cause undue pain to your partner and prevent you from experiencing the pleasure of being able to plunge completely into the experience. Pun, um, still intended. Even a guy who is quite below average in the length department (less than 4.5 inches, or 11.4 centimeters) can make up for the deficiency by engaging in more preintercourse pleasuring and by trying some creative positions [source: Ask Men].
Enough already; this discussion is getting, well, embarrassing.
