Ive always had a problem with how tight my foreskin has always been but only when erect, well i finally took the plunge whilst in the bath i pulled my foeskin back to the head and got an erection however there was slight pain mainly on the tip the head but nothing that would make me yell out loud, If i have it circumsised then i wouldnt really be making much progress other than cutting out a very dull small pain.

Should i keep my foreskin pulled back during the day and just leave it so that maybe it'll slowly expand the skin or will it cut off the blood supply?

any one else outthere got the same problem?
