Confused about my sexuality

I have been wondering about my sexuality for over a few years now. 2 years ago I realised I was bisexual, it took a long time to realise because I’ve only dated guys but I realised it when I was 15. As of last year one of my friends came out as asexual, I had never heard it before so she explained it better to me, after a while I started feeling like I was to, but the thing is at the time I got turned on from porn and my boyfriend. So after another long time of research I thought I was Demisexual, it explained me perfectly. As of the last 7 months I haven’t been feeling that way anymore, I don’t want to do anything sexual, and even thinking about it makes me feel super uncomfortable, nervous and even depressed. I don’t know what happened, nothing has changed but I just feel so weird about it..could I be asexual? I still get turned on from porn but it’s rare. Is there a name or community for feeling this way? It makes me feel more valid knowing there’s other people that feel the same way as me

Sorry if it was all over the place! Feel free to ask questions if it’s confusing :))
