Advice needed

I am currently questioning what is going on in my life and I need some advice on which label might fit and if I belong in the asexual community, if I belong partially or not at all.

The situation is as follows: I am a polysexual non- binary person, but through my whole life I have felt phases, lasting anywhere from a few weeks to a few years, in which I have felt strongly sex repulsed and did not feel any kind of sexual attraction to anyone. Still at the other times I am hypersexual and feel very strong sexual attraction. I have never had to think about it until now as I now am in a relationship and my partner has a high sex drive and corresponding sexual attraction, but now I have shifted into my very sex repulsed state and I don't know if it might affect our relationship. So I have turned to searching for something that might help me understand and explain.

Is there any label in this community or any else that describes what I feel? Please be kind, I have literally no idea what is going on.
