The first thing you need to know is that even after a whole history of interest in genitals and sex we still don’t know for sure what the average male genital size is. It’s pretty strange to think that such a simple issue is still unsolved to this day, but the fact is that this issue is anything but simple.
The bottom line is that scientists have yet to pin down the exact average size and it looks like this isn’t going to happen any time soon. Studies on penis size cannot be trusted at this moment because a lot of men are embarrassed with their size and they won’t come out and be measured.
