Hello, i want to know about the correct penis size of a teen boy(21 years old) would be. My penis is now 6.5"(when erected). Is there any exercises to make my tool more long naturally without using any foreign instruments? Please answer genuinely.
Well I'm 20 and I'm 6.5" just shy of 6.75" long with 5.5" girth. We're above average already since average is 5.5".
