ive heard about a bit of this kind of stuff in the body mod world... a lot of times its something that the person has wanted to do since they were very young and just never did for whatever reason...
and why would they try it on themselves... well what doctor would agree to it...its almost impossible to find someone that would do it, even for someone that was sane...
heres a couple articles if yall wanna read more bout this type of thing...
