Hey guys, i'm 15 almost 16 and never stretched or pulled back the foreskin fully. as of recent, i have been trying to pull it back but when i get say 3 or 4 cm passed the top of the head, i get worried that it will get stuck behind the 'rise', and my nerves will jump 30,000%. Should I just pull it back as far as i can. Or should i gradually pull it back a little further each day? My main concern is that the foreskin will get stuck. Any advice/help would be appreciated.
