Question for allosexuals: does remembering sex with your ex feel disgusting or nauseating?

This might not be the right subreddit to post this on so if it gets removed that’s understandable.

For those unaware, allosexual means people NOT on the asexual spectrum, people who experience relatively frequent sexual attraction towards others.

I am asexual (I might be demisexual but idk honestly). I have dated one person before, my now-ex-boyfriend, and he was the one and only person I can say I was ever genuinely sexually attracted to. I had a few sexual encounters with him and they were fun at the time. We dated for a year and a half, we were long distance for most of it, and we broke up 5 months ago.

For a few months leading up to the breakup I could feel myself falling out of love with him and sexting with to him became more disgusting and unpleasant for me. But I still loved him so I did it anyway. Since breaking up with him I have noticed myself being more sex-repulsed than I was before (my feelings on sex itself used to kinda shift one way then the other). I don’t think I ever want to have sex again. The joy I felt in the moment is now eclipsed by the pure disgust I feel about it all now. It feels so wrong in retrospect.

I have intrusive thoughts and sometimes those memories are brought up and it feels almost nauseating and disgusting to me. And he wasn’t a terrible guy to me, he treated me pretty well but there were just some things about him I couldn’t tolerate anymore and I grew to resent him because I didn’t voice my feelings enough which I take full accountability for.

So I guess I’m wondering if this is an asexual thing or a post-breakup thing? Do I feel this disgust now because I’m asexual or do allosexual people also feel this way about their ex after a breakup. I’m curious for feedback. Thank you.
