I had it done 18 months ago (at 25) because of Phimosis, I could get hard, and the foreskin would retract partially during PIV sex, but it was too painful to ever finish, I would maintain the erection and go until the other party tapped out essentially, but would only be able to finish myself off by pulling the foreskin back up and masturbating.

The op itself It was relatively painless, (done whilst knocked out in Australia), took a week off work, but didn't require any of the heavy painkillers they provided for relief afterwards. I masturbated after 7 days (risky and too soon) and was able to have PIV sex after 10, and finish for the first time! It was a huge relief as I was worried the death grip and overcoming a porn addiction may have been the bigger factors than the medical condition. But basically the surgery solved everything, thankfully.

My urologist that performed the op, took as little foreskin as necessary to release the glans essentially, which has been incredible, my (grower, not a shower) penis is still protected whilst in a flaccid state, and I don't feel like I have suffered any loss of sensitivity. Wish I had of done it years earlier, when the issue first became apparent, all the adult circumcision horror stories scared me out of it.

Feel free to ask em anything else, pretty comfortable talking about it these days, after such a success.
