i am 18 and i cannot retract my foreskin i have no pain when i am masturbating.i have read that moving up and down our penis may retract the foreskin after some weeks.how long this is good.please tell me a way to retract my foreskin.
You can stretch the foreskin by getting an erection and pulling down on the shaft skin OR use your fingers to spread the opening.
It takes some time but the more you do it the faster the results.
You don't want to force the foreskin back but you do have put some pressure on it. There may be some discomfort, don't hurt yourself.
