Penis Size Matters One of our friends debunks the myth this way: “It’s not the size of the wave, but the motion of the ocean.” There are a lot of different ways to phrase this, but it comes down to one important question: Does it matter how big the guy’s penis is? We will start by looking at whether penis size matters to men who have sex with women, then whether it matters to the women themselves, and then whether it matters to men who have sex with men. If you ask your friends, you might hear all kinds of answers to this question. Some claim that size does not matter at all as long as the man knows how to use their penis well. Others swear that the best sex of their lives was with a particularly well-endowed partner. And some will say that sex with an exceptionally large penis was not enjoyable, and even painful. Both popular opinion and surveys suggest that men are very concerned about the question of how big they are and how the size of their penis compares to other men’s penises.
