No thanks, having someone mutilate my penis is not my preference.
Actually, I once checked out of curiosity, and, apparently, if you convert to Islam, you are not expected to undergo genital mutilation, only if you are born as a Muslim. There is also a small minority of Muslims who follow the Koran but not the Hadith, the idea being that the Koran is the Word of God, whereas the Hadith are just useless Arabic folklore/customs etc. Since circumcision is part of the Hadith and not the Koran, they do not recommend it. Mohammed wasn't circumcised, you see, plus, (I think?), like with Christianity, the human body is deemed sacred as it was created by God/Allah and therefore cutting off essential parts could be deemed as being sacrilegous.
Cutting out alcohol would be no problem(!), cutting out pork/wild-boar would be a nuisance but bearable, being forced to grow a permanent beard a la Isis would be an issue unless I get this Wim Hof Method under control.
