I'm 17, I usually masturbate every day, however, I have never been able to pull back my foreskin while flaccid or erect. This in the last year has given me difficulties cleaning my penis, urinating and sometimes ejaculating. My penis is sometimes red and itchy after masturbation too. How can I pull back my foreskin? Any help would be appreciated.
I would add pictures if needed but I'm not sure if I'm allowed.
