Genitals size growth, now it is like 4 inches

Hi Guest,

4-5" is average for a 15 year old.  Being overweight can hide part of your penis though.

It can grow into your early 20's.  Average for an adult is 5.1".

Hope it helps.

I once heard Dr. Oz say you lose an inch for every ten pounds you gain because the fat grows out over it. I don't believe that because I had 7 inches when I weighed 135 pounds. When I weighed 245 I should have had a 4 inch deep vagina but I didn't. I just needed a mirror to see it because my belly was in the way.
