There are no realistic health issues involved. The majority of people have been uncircumcised since people were invented, and the entire animal kingdom gets by fine without circumcision.

Be aware -- asking this question is like asking guys if they like their penis. It's a subject more fit for instinctive and deeply felt reactions than discussion. You're not going to get a lot of circumcised people saying it's unnecessary or somehow not the best idea. The impact of religion and culture on the issue is pretty overwhelmingly determinative, too. Match up cultural and religious norms with deeply personal self-consciousness on a primal level, and you're just not going to get a lot of people saying let's call the whole thing off.
