I had a shower and retracted my foreskin, though after I noticed that when I had pulled it back over the head that some of it had stuck to the head. I have had this problem before and the normal solution was masturbation, though this time I felt a lot of tension on the string between my penis and foreskin. I have tried pulling it back and even trying to pinch the foreskin back over the top but nothing seems to be working. Any advice?
