when i talk with girls sperms comes out !

Are you nervous when you talk or are your thoughts of a sexual nature.
If your answer is yes to any of the above try and calm down.
if it is No then
In my opinion as long you are the only one who knows.
It might jus be how you are learn to live with it

ya I`m nervous. cause this is my first time I`m in love !

You could also try masterbating until you have an orgasm before you go talk to her. That could stop it for a little while.
