ive read that you should pull back your foreskin often so that you can stretch it out. I have phemosis and it really isnt enjoyable. i dont like it. it sux. ppl say you can pull back before an erection and allow the erection to stretch it. but ive tried and well its kinda painful.
As long as you can pull your foreskin back when you are soft, to allow you to clean your penis properly, that is fine. Can you masturbate OK with your foreskin foreward? I'm sure that you can, and you won't have any problems having sex either.
