I have arm pit and pubic hair but still can't produce semen

Hi Nick,

You appear to be in puberty.

Have you ever had a nocturnal emission?  A "wet dream?"  That's where you wake up with sticky shorts.

What happens when you masturbate?

Very few penises are straight.  Most have a bit of an arc to them.  Remember too, you are still growing and things can, and will, change.
