Why do you think?
A female does not have a penis. Only a male has a penis.
When your girlfriend tells you "You have a weak penis" or "Your penis is weak"
She will only admit she does if her boyfriend has a big penis.
If she enjoys it, and has pleasure then keep doing it with her okay... if it gives her pain, stop and do something else.
That's called arousal - and if you don't know what that is, or why it happens - it's time you started paying attention in class !
maybe not...:)
I am 15 to and mine is only 3 inches soft and 5.5 inches hard its fine me and my friend hes 11 we sucked each others penis and made out so and his is only 3 inches hard but it sure tasted good .
no only when u get aroused the bone siftens or become firm
Yes only if your penis penitrates the hard protective plastic barrier/
When your wife walks in on you and your girlfriend.
it depends on wat the girl did or is doing to the guy, but if the guy has a girlfriend then he should get hard only over her.
