Re: Problem when mastrubating with retracted foreskin
I had read more than five times to try to understand what you're doing.
First paragraph said no problem with the ejaculation. It's normal, when foreskin is still covering the head, some burst will flow around the head. Even more if you pressing and shut the foreskin tightly when ejaculation happens.
Second paragraph mentioned the head became large. In fact, penis shape in erection state, will be different if your foreskin still covering the head, than when you pull down the foreskin.
You said the ejaculation did not flow around the head when pulling down the foreskin. Okay, that is the peehole where the sperms come out. Because there are no barrier, then lately burst which is weaker, some liquid may left sticky at the peehole.
Don't worry, it's normal if this is the condition. Just clean it with water or pee-ing it away.
