As the legitimacy of penis enlargement becomes more accepted in our society, many men find themselves asking the question: "exactly what is a small penis size?" The truth is that most men don't really have a strong reference point to determine whether their own penis is big, small or an average size.

The truth is that heterosexual men rarely see other men's penises. The one exception is in adult films, but those men are often chosen specifically because they have large penises, and they certainly don't provide an accurate idea of the average penis size. Some men mistakenly think that they do, and it can make them feel very self-conscious.

The Research

Only recently have researchers begun to do proper studies of men's penis size. Obviously there are numerous challenges to doing an accurate study, since penis size can vary widely on a account of age, race, or even time of day. The most effective studies measure erect penises in men of varying backgrounds aged 20 - 40, and rely on measurements from medical professionals, rather than having participants measure themselves. These studies have determined the average penis size to be 5.1-5.9 inches (or 12.9 - 15.0 centimeters).

In the end, a man's decision to pursue penis enlargement should be his own personal choice, and shouldn't be based on statistics like these. But everyone is curious, and every man has asked himself at one point "just what is a small penis size?"- there's no denying that! Some men with an above average size will try enlargement just to see how big they can be, and some men below the average will still be content the way they are. But if you've read this far, you're no doubt curious about enlargement, and it's worth it for every man to at least know a little bit about all the options available to him.
