hi guys n gals, i am 19yrs old and have phimosis i think... i cannot retract my foreskin over the glans. should i be worried? some websites have said that the foreskin should be retractable at puberty, some say at 18.it doesn't look like my foreskin is going to retract anytime soon... i dont want to get circumsized, i want to try streching? is there any excercises i can do, because it is very painful if i try to retract the foreskin. any help would be appreciated. thanks,
