Nothing much to add, except to voice support for what's been said already. If you aren't already, you might try using condoms for a while. They help decrease sensitivity as well.

Good Luck.

I'm with wally on this one...he should check with his doctor ASAP! It may make him feel uneasy, but he's going to need to see him as part of the post-op follow-up, so he might as well tell him about what's happening.

I would also strong urge you to have HIM focus on YOU for a while. Stay clear of his penis during foreplay. Full body massage, toy play, oral sex (on you). ALso, as Wally said, just because he cums, your sex should not stop - especially given his medical condition. Go for round 2 and 3 if need be. It's my gut instinct that the head of his penis is so overly sensative due to being "sheathed" by his foreskin for so long, that almost any touch will send him to orgasm. Over time his body and penis will adapt to being fully exposed and he should expect to enjoy a "normal" sex life.

You can also visit a local adult bookstore and purchase "desensitizing" cream. This is a very light topical anisthetic (kinda like anbasol for a toothache) that should help prolong intercourse.

Hang in there!

Hmmm.... sounds like a question for the doc during a follow up visit. I suspect (and I'm really not trying to be cute here) that lots of sex and orgasms may help. It might help "desensitize" him.

As for "lasting longer," two thoughts:

One, avoid directly stimulating him. For example, play with his balls without touching his dick. He'll love you for it.

Two, remember that just because he cums that doesn't mean it's over.

And, if I can add a third, "don't worry too much" about it, provided you are both leaving the experience satisfied and content.
