I wouldn’t personally care, post op or no post op but I understand why for some it would be a major turn off.
My experience. She was very feminine but I can see why some people might be unsure. Either way, she’s hot and very sexy. I did fuck her pussy for a while but spent more time in her ass (which she clearly enjoyed more) and didn’t go down on her. Why? Not sure but her blow job was soo good I was happy to have that. She was a great kisser, insanely passionate, and provided a really good service. I have had some TS experiences (not for a long while) so doesn’t bother my either way.
I would genuinely be 50/50. If the idea is a major turn off I wouldn’t book as I suspect you’ll be thinking about it and distracted. But if you do book she’ll snog your face off, suck your cock like a pro, and screw your brains out
