Well not every one is built for larger sized penis. All women are built the same but differently, some are deep and some are not. I bet these girls have been 5"8 or under, but to me 10" is fine but that's not to big.
Things to keep in mind, however, include:
ask your mom!
mine is 6 inches...
An erect adult penis averages 5-5.5 inches in length. If your penis is already 8 inches long, I would assume it has reached its maximum growth.
about 5 3/4 inches
A normal 24 year old would have a penis of between 5 and 7 inches long.
It would be alot harder for a guy to bum you and you'd crap through your penis and your girlfriend would dump you !!
I would say about 5 inches long
The average male penis is 5.1 to 5.9 inches so I would say you are well-endowed.
about the length of your penis.
No, if there was, we would all have 2 more inches.
I am not a Mulatto, but I am a doctor, so I hope that qualifies. The average penis size for an adult male is 5.5-6.0 inches as measured from the top of the penis. If your penis is 5.5 inches, and was measured from the top, then you would have an above average size for your age, since your size is the lower end of normal for an adult. Your penis will continue to grow for another few years.
That depends on whether you are measuring your penis while it is flaccid or erect. A flaccid penis would be about 3 inches normally. An erect penis is usually 4-6 inches.
