I was cut shortly after birth, and have had no problems with it. I've heard talk that guys who are cut have less sensation than guys who are intact. How would we know that if this is all we've ever known?
The only guys who would know the difference are those who've had sex uncut and then got cut. It's not like all of us that are cut are saying every time we have sex "well, that was good, but it would have been better if I hadn't gotten snipped."
I have a urologist in the family and he does quite a few circumcisions from young guys to older guys, and they've all said they enjoy sex more after the circumcision. But you have to remember that these are men who had foreskin problems that were preventing them from having satisfying sex lives.
As far as what women think. They have their preferences but if they're really into a guy I don't think they really care all that much. In Europe most men are uncut so that's all the women ever experience.
Cut or uncut, they both look more or less the same when erect.
