feeling guilty for wishing my fiancé would just be a woman

first off i've tried to post in multiple lesbian/lgbt oriented subreddits but karma limits suck and my fiancé follows my main acc. so pls refrain from making any homophobic/transphobic comments, and pls be civil with advice! :)

so i (21f) have been with my fiancé (20m/unlabelled) for just over a year now. i am like, over the moon with them, but i just... feel guilty that even though i am attracted to them and their personality and their body i just can't seem to be fully attracted to them as much as i'd like to be? i struggle with the fact they're confident in an identity and presentation that leans more towards the masculine side, and even though they're happy presenting somewhat feminine (long hair, skirts) i just find it isn't enough, even though i respect the fact they don't want to take it any further than that, and i have shut up and not pushed it further since i understand my attraction shouldn't factor into their wants for their appearance and identity.

i just find myself wishing they had smooth skin with no/minimal stubble, no/minimal chest hair, boobs... i wish they wanted these things too and i feel so insanely guilty for that. especially since i'm so fussy about this and yet i absolutely adore their genitalia (they were born with a penis and don't want bottom surgery or anything) - so i feel like a weird sexual freak.

it's worse because if they looked like they do now but they identified as transfem and were actually willing to even slightly transition (as simple as wearing feminine clothes more and putting an active effort into looking even slightly feminine specifically) i would not be having a problem with my attraction whatsoever. i feel like its just the fact they do kinda identify with being a man or masculine-leaning despite not labelling themselves with any gender as a whole.

idk, is this something to feel guilty about? or am i just feeling guilty for actually just being a lesbian even though my lesbianism should include all non-men 😭😭
