At 14, I was 5'7" with a 5" erect penis. At 16, 6 months till 17, i'm 5'9" with a 5" penis... Does your penis grow at a different rate than your body? I am not fully developed yet as I don't have sideburns and my facial hair is still patchy at best (though I do need to shave every 3 days). I am very insecure about my penis size, and am worried if I will be able to please a women. Another thing: instead of feeling pleasure when I rub my head it tickles, but the area right below the head on the inside* of the penis gives out normal pleasure; is this a sign of underdevelopement? Thanks for any and all help.

*to clarify, part that faces outwards when erect
