Really? I didn't think there were many people in the UK that were circumcised, assuming your even from the UK that is! Personally I feel the prepuce is there because of some evolutionary advantage and because of that I wouldn't like to be circumcised. I also feel that it would be a bit weird cutting of part of your body however small it is unless it's causing major irritation/problems.
I don't know how a man could reach orgasm without it either but maybe it's not as different as I think. However I doubt it would have any effect on the feeling at the receiving end during intercourse.
If you're interested in other people's perspetives - there are a few threads on this knocking around in the archives....very interesting :)
Personally I prefer to feel naked skin!
The first time without a condom was incredibly intense and intimate for us!
I do however love condoms when going through a painful spot - they make him slimmer and sleeker for insertion!
