My friend and I have never had sex, I always use my hand and his finger for me. But I always wonder when I am jack him off this clear stuff shot out. But soon after that he cum, and he never notice this clear stuff. Is the clear stuff pre-cum and do a guy pre-cum just one time?
Yes that is pre ejaculate. It has semen in it just like the regular ejaculate. He might not notice it because it is so close to the time that he ejaculates that his mind isn't even paying any attention to it.
