Well, the papers today are full of research which appears to show that circumcision is remarkably effective at stopping you getting HIV/Aids, at least from heterosexual sex. That sounds like a significant benefit in anybody's book. Mind you, I'm not totally convinced: I believe the research was done on adults who had been circumcised, and covered a couple of years after the operation. Maybe they were just a bit sore, so didn't bother about much activity for a while?
