My attitude is that it's a choice, but the key thing to remember is that once it's gone, it's gone. Personally, I wouldn't advise parents to make that kind of decision for their children, mostly for that whole permanence aspect. And the aesthetic thing is really just subjective. Medically, people tend to be divided on the benefits, there's probably some benefit, but I'm not really sure it's going to be the end of your child's life if you don't circumcise him. As far as sexual pleasure goes, I've generally heard a consensus that the foreskin does act as an erogenous area (not to mention first-hand experience).
In summary: Hey, I'm not you. Make your own choice on this one. But, if you're a parent, maybe consider the fact that your son might like that same privilege too.
[Although, I forgot to mention that I have no issue with circumcision of an infant if there really is a decent medical reason for it. Thought that went without saying, but people can be kind of nitpicky sometimes]
