> I remember reading an article on her website years ago about her transition
It may have been a link to her '79 Playboy interview, where she talks (shockingly for the year, IMO) frankly about her transition and the realities of being trans: http://transascity.org/files/history/Carlos_Wendy_Playboy_In...
It talks about her music, but also dives into things like masturbation post-operation, sexual encounters before and after, and more.
Her closing statement seems to align with your summary, but goes even further:
> Wendy: [..] I think I would feel happy if a reaction to this interview were a yawn. I mean, who cares? I've gone through a procedure. It's done with. Just let me live my goddamn life and I will let you live yours.
> Playboy: It's certainly not boring. And by doing this interview, you're showing that you do care.
> Wendy: I don't want to become a proselytizer. I don't want this interview to champion the cause. I think it's very important that my condition be acknowledged as very rare, so that it's seen as a highly unlikely solution for other people with an unhappy life, or suicidal impulses, as I had. The fact that there were some "successful' transformations doesn't erase the many tragic cases in which an operation was not the full solution for particular individuals. No one should follow this hellish path if an alternative exists. Try other options first.
