I'm uncut and American. I haven't had any problems, though I did hook up with a guy who had never been with a guy with an uncut dick. That wasn't a problem, though, as they didn't filter guys based on cut/uncut status.
If anyone is wondering whether or not to circumcise an infant when it is not medically necessary, lean on the side of caution and do not circumcise. When the child is old enough to have sex, they'll be old enough to decide whether or not they want a circumcision, and can decide for themselves.
