The thing about circumcision is that it is on the way out, today I think only about 30% of babies in Toronto are circumcized. I am not, because my parents were hippies, where 90% of the guys my age are. But it will become more and more associated with being old.
Would you let someone slice your penis? What if he screws it up? Is does happen. What if it gets infected? No thanks.
I once had a lady, while she was sucking my cock, mention how much she hated sucking uncut guys. When I pointed out to her what she was sucking, she was shocked. She did not realize that for some (but evidently not all) guys, the foreskin retracts automatically when the penis is hard, and you can not tell it from cut.
