for the past few months ive been reading up on retracting the foreskin behind the glans and did mos tof my stretching while i was taking a shower. Im an 18 yr old male and it wasnt up until 3 weeks ago that i pulled the foreskin back and now i can do it with ease while flaccid, although i can only pull it half way down while erect and i can probably pull it all the way but it'll hurt too much. But the main problem i have is that i kept it rolled back right before i was going to masterbate and got an erection while it was rolled back but it hurt alot around the frenulum, ive done it a few times now and seems to be getting a little better, maybe its just because i started retracting it? will it get better if i keep doing it? has anyone else had this problem?
