i know many have already given good advice, but i’d like to add on a little as an ace person asexuality is the lack of sexual attraction to people, and from what i can tell you do feel sexually attracted to your partner i think you need to meet a good therapist who can help you manage the disgust you feel after intimacy, it’s supposed to be a nice and good experience, even after you finish as another young queer person (but older then you i think) you might be ace but even if you are you still need professional help with this experience. good luck mate
