as the title says. i'm a lesbian in my early twenties, and until now had only been with other cisgender women. i went on a date with a woman i met online, during which she disclosed that she was trans (i am completely fine with trans people and i appreciated her telling me before anything happened. this was someone who had a generally feminine face and androgynous build, so i didn't expect it). i did let her know though that while i thought we vibed well thus far that might be a dealbreaker since im only sexually attracted to female anatomy. she assured me that she had had the surgery, and was respectful either way. she said (from my memory) "it's all healed, so it's the same as a cis woman's" from lubricant to reaction and feeling to taste etc. to me that meant we were good to go.
we went to her place and ended up having sex (i know sex on the first date isn't a good look for me) and i decided to go down on her first. when i got down there, the visual was normal. but the smell was just off like mostly salty sweat and something sweet in a bad way but of course every cis woman is different too, so i thought it was just an individual thing or maybe she hadn't expected this and didn't clean up enough. i got in there anyway with my tongue and that same scent/flavor only intensified and once my tongue was inside i felt what can only be described as hair-like in there with the tip of it (it felt very coarse so i know it wasn't just a weird sensation i imagined or something). now, i have a sensitive stomach anyway and i pulled back and threw up on the spot. i felt absolutely horrible even though she was very kind about the whole thing but i just know i made her feel bad and i just feel awful we spent the night cleaning vomit off the bed then going our separate ways. we haven't chatted at all since. i feel like i should say something but i don't know what to even do and i feel so shaken up by the whole situation, because i feel awful to have done that to a person but i also feel selfishly like i was a little misled? i don't even know. i never want to make a person feel bad especially because she couldn't help it but i feel so awful in every way.
