The hole (let’s not insult women and call it a vagina) is created by hollowing out the penis, drilling a hole into the pelvis and then putting it in inside out. The balls are also hollowed out and the outter labias are formed with them. There‘s no inner labia as far as I know, but since women are expected to look like porn stars and even being shamed for having visible inner labia, even get their inner labia cut off, this is exactly the goal of the surgery. So there is sensitivity when done well, on the outside as well as the inside. And the stretching only needs to be done for half a year. He got his for free in Thailand (don’t ask, went down a rabbit hole over the holidays lol).
Personally, I think he transitioned primarily because there are endless surgeries available for women. As a man, it basically ends with lipo and abs and he hit the wall, as Jessica he unlocked an entire new world of surgeries, becoming female was just part of the package deal he had to accept in order to get his fix. It gives me anxiety thinking about the day he gets therapy and realises what he’s done
