My question is related to the situation I'm facing with my foreskin. I'm able to retract it comfortably when my penis is flaccid but it's hard to do so during erection. I'm able to slide only a little over the penis head when it's erect after which it starts to pain. My foreskin is attached to the penis (frenulum). I'm able to masturbate without any pain but then, I don't pull back the foreskin during masturbation. I wanted to ask is there any way I can retract the foreskin during erection with ease? Will I've to undergo circumcision?
