i get terrified whenever i see my partner naked, even tho i love him. how do i get over this?

i do want to be with him, and i do fantasize about him a lot, but if he just prompts me sending a nude, or undresses in front of me, or whatever, i feel this uncontrollable dread, and i feel like there's something wrong with me. no, it's not about me not wanting him to see me naked (edit: i mean that is also a problem with me, but i don't think it's related here). and this was also a problem in my previous relationship. i really love him and want to satisfy him, but now i'm even scared of the fact that i'll get triggered next time. just what tf do i do here?
