All my brothers have been circumcised. They think its great. They werent so happy at the time, but, they had to have it done for medical reasons. We had DS checked out too because it looked like he may have needed to be circumcised too. However, we went to our GP, and saw an everyday, common or garden urologist, who decided it wasnt a necessary operation on balance. (Factoring post-op complications, infections, general anaesthetics etc).
So yes, it can be done for medical reasons, but, if it hasnt caused you a medical problem in the first place, why get rid - most men go through life without a hitch.
Same way alot of folks go through life with an appendix without a hitch.
