Hello! I'm not the person you asked but I figured I'd throw in my experience.

In my case, if I could snap my fingers and instantly change my penis to a vulva, I would. But I had a haemorroid surgery many years ago, and the month or so afterwards was one of the worst times of my life, so I would prefer it if no surgeon ever went anywhere near my lower trunk ever again.

But everyone's experience is different. Some women just like to fuck, and of the trans women who do, some don't feel the need to replace the factory installed equipment for doing so.

Well, you could still pee standing up.
