Would a shy, 13 year old guy think about sex with his first gf?

I reckon they do.. but my little cuz dont beleive me (about her bf)

YES and in a big way. 13 and 14 is a very active time for a boy,and that might be all they think about, but girls are risky to them. They are still not too sure how or if they are doing it right.

Mastubation is far safer and more common then a relationship. Even the first time is a very difficult deal for just about every one, but I think the question you stated was more about if sex was on their mind, and the real answer is YES and in a very big way.

Masturbation started long before then if he has a foreskin, and even if he is cut he might already have found out how to do this. Maybe from a friend.. A BOY friend... That's right ! A boy is just like him and safe grounds... Its not a gay thing its more like a safe thing..

All boys compare equipment at least once in their life. How else can they know they are normal... None of this implies a homosexsual future and its all normal.

Hope that spells it out. Make no mistake... 13 14 & 15 are very active years for a male, but he has a lot of growingt up to do yet.

Your real answer.
