Are you Average? More? or Less?

To some men these are very important questions which this site attempts to deal with in a sympathetic and understanding manner.

For these men penis size IS a problem.

In the early 60s, The Kinsey Institute conducted a survey amongst US College students of Caucasian origin about the sizes of their erect penises.

Whilst the data may not be representative of the US male population – restricted to a defined age and ethnic group – it nevertheless enjoys a wide degree of credibility.
However, in the absence of information collected by more scientific means, it is still regularly quoted in connection with the subject of the sizes of erect penises.
As can be seen from the first table, the most common size range is from 5.5″ up to 6.5″. This size range comprised over half the surveyed participants, whilst over 20% of the men had a penis that was smaller than the lower end of this range. Looking at the bottom table, the most common girth range is from 4.75″ to 5.25″. Over 47% of the men who took part in this study had a penis that was thinner than this median range.

As can be seen from the above figures, about 20% of men in a survey have an erect penis length that is less than 5.50 inches.

These are most likely to be the men who have difficulty in sexually satisfying their partner, and would benefit from undertaking a program of penis enlargement.
