I've been reading around recently and was masturbating and tried to pull back my foreskin to masturbate but it hurt a lot. I knew that there was a little bit of skin from my foreskin attached to the glans right by the urethra opening. I'm 18 years old and didn't realize that it's not normal to have the foreskin attached to the head. It is not a bother unless the foreskin is pulled back too far while flaccid or when it's pulled back a bit while erect, where it'll hurt a lot and turn red.
What can I do about this? I don't want to be circumcised.
EDIT: After a bit of further research and talk with some friends, I've come to the conclusion that what the actual issue is that my frenulum is just a bit overly sensitive and that I shouldn't really have anything to worry about right now. I wasn't really aware that the frenulum was a thing but a friend showed me some diagrams and I thought (oh wow, yeah that's right). Like I said before, I don't have much to worry about but if anything ever changes in the future I can consider a frenuloplasty.
