Hello, Im 16 and just recently decided to start pulling my foreskin back. I can do it easily when im not erect (Theres no problems at all) but because of the "lack of doing it" i end up getting a boner...Now when i have an erection with my foreskin back the band behind my head is really tight and hurts really bad (To the naked eye it looks like it starts to turn purple as well)...Anybody know what I should do or perhaps after doing after about a week the band will losen itself up??
