It's just a slave initiation practice, where it denotes submission and, consequently, membership into the tribe (of slaves). Same way they do it for the birth certificate or the retarded haircuts by the manchurians or cutting off yakuza fingers. 

It also enforces the idea that sex is strictly for procreation, not for pleasure.

any spiritual person worth his salt will know that you dont need to mutilate the body for its a manifestation of the entirety
its like placing yourself above the father of preexistence with a 'I know better' attitude and results in demonic possessions
