sex life as a trans woman

Ho, I don’t really know how to start this, but i’ve been seeing this guy for like 3 months, we’ve been on multiple dates and things are getting really serious, the thing is he wants to have sex, but i’m so uncomfortable right now in the sense that my bottom dysphoria is so bad, idk if i’d be able to go through with it. He’s never been with a trans girl before and although he’s fine doing it, i just have alot going through my mind, and what he’ll think when we’re intimate 😭. I’ve been on hormones for a year and 3 months and ive not been with anyone sexually because i feel so dysphoric in my own body, i feel like i won’t be good enough for him. Anyone has any advice or went through something similar?
