I don't know if getting his dick lopped off would really change much. He's already pretty open about estrogen having destroyed his sex drive, so it's not like he's jerking it anyway. He's still a creepy sexpest because that's what he's always been and it's pretty much instinctual for him but I don't think he really 'gets off' in the traditional sense to it at least. He also seems to have a good pain tolerance when it comes to such things, as the un-clit has shown. Might even make him happy for a bit. He's too dumb and delusional to realize it's just a gross open wound, so he might genuinely think he's a woman if he has it done. Who knows, though.
