Questioning my place on the spectrum

I've been celibate for almost two and a half years now and it's been easy as shit. BUT in recent weeks I've been thinking about sex way way way more than I used to.

I don't like *want* to have sex but I've been thinking about it so much it's bothering me.

Has this happened to anyone else? Is it normal to wonder how ace you actually are after believing it so truly for so long?

I found a lot of comfort and questions answered about myself by asexuality but I'm confused about who I am now and it's becoming very mentally taxing
