I've been with guys who have been circumsized, and guys who haven't. Actually more guys who haven't. In America, there's kind of a medieval view on the subject in my mind. The rest of the world doesn't practice it and everything is rather fine actually. The "health" issue is so minute that anyone who takes even a small amount of care it becomes a non-issue. Plus the heads are softer, the foreskin gives a nice gliding motion (which means they can often go longer in my experience), and it has kind of a nicer taste. Well, not nicer actually. But more of a sexual taste I guess. Either way I perfer it and from what I've read/heard it's more enjoyable.
