I realize you haven't specifically asked for advice here so pardon me but I must say my first reaction to this is concern that you may be diverting from your true desire, which is for nullification, because of the sense that vaginoplasty is similar or equivalent to nullification. This might be a mistake in several ways.

Number one is of course the question of complexity and complications. Nullification is probably the simplest form of full bottom surgery with the least complications, vaginoplasty the highest. Google Ai says the following. "Maintaining a neovagina is a lifelong process primarily involving consistent dilation, meticulous hygiene, and regular medical follow-ups." Nullification, on the other hand, simply requires that you sit to pee afterwards. We're talking two extremes here and it kinda pisses me off that we're not generally free to talk about it.

Number two is equally important. I presume you are a bottom and already receive sexual penetration in the "normal" way (lol) and, if my own experience taught me anything it's that being "cunted" in that way is both transformative and euphoric. We all respond to anal penetration in our own way of course but I think it's a mistake to presume that "front hole" penetration would be as good or even better. Sorry, but that's just not realistic and for a guy who embraces nullification to devert from that sublime course because......well, conventional prospects?

I apologize if I'm coming off as an arrogant dick(less) here but this is all meant with the best of intentions and even love. You decided you want your external genitals deleted......amazing! But why allow yourself to go down a whole other rabbit hole? Just my two cents. Nullification is legit! S'all I'm sayin!
