Re: what a weird question for guys.
I remember, when I first masturbated at the age of 11 or 12. When I had orgasm, I don't think there was a lot of semen at all! These days (I am now 14 and a half), there is so much, I don't know what to do with it!
As for sex, yes. I definitely am ready. I actually have quite a large penis, you know. Maybe a little too big. 12 cm, I think.
