I'm not sure there is any such thing as an 'unhealthy' sex drive! Hasn't research shown that most men, of whatever age, think about sex at least once every five minutes?
I was circumcised at my own choice two months ago, after many years of wanting it, and it has greatly enhanced my sexual experiences. I'd kept my foreskin permanently pulled back for four years previously, so the glans has had time to 'desensitize', which it simply has not done. I agree with ukboy and bojohn - nothing but benefit. I have also chatted with many, many, other guys online, and they all say the same.
If being circumcised is something you really want to do, for whatever reason, then do it now. Otherwise it will niggle away at the back of your mind until you do.
