Male circumcision is NOT anything LIKE female circumcision: Men can still enjoy sex afterwards, women can't. If male circumcision was such a traumatic thing, God would never have insisted on it in the Old Testament.
The benefits of it: It is proven that circumcised men are less likely to contract STDs, less likely to develop a urinary tract infection, and nearly zero risk of penile cancer. Circumcised men are less likely to give their female partners the human papilloma virus (which causes cervical cancer), have nearly zero chance of developing balanitis (infection of the head of the penis), offers better and easier hygeine, and better sexual stimulation.
I think that, instead of banning the practice, perhaps the law should stipulate that males make their own choice on the matter when they reach a certain age.
