Look at what you're arguing. You are arguing that FGM is different than circumcision because guys can still achieve orgasm after circumcision. So, the issue for you isn't if we are mutilating children's bodies, causing them pain, etc., but instead, it's whether they can still achieve orgasm later on in life. Unbelievable.
I also suggest you look at those who have been circumcised having decreased sexual sensitivity. So, how is this any different than your protesting of FGM based on sexual pleasure decreases?
Further, you may want to check out Africa. In many areas there, FGM is done by Christians. It is more of a cultural issue than a religious one in many regions.
Face it- your stance against FGM is based on it being foreign to your culture. The fact that you have no problem allowing the same damn thing to boys based on it being acceptable in the culture you were raised is yet another example of sheer hypocrisy shown on this board.
Religion- ain't it grand (and that doesn't exclude the hypocritical Christians on here).
