So I thought I was asexual… But I sometimes get turned on my thinking about this guy I’m in love with (it’s long distance too) just full on fucking me till I see stars and dirty talking to me… Is that like really weird?

Nope! Just sounds like your sexual needs aren’t that easily defined. Having sexual desires for someone you love is perfectly normal. I wouldn’t worry so much about putting yourself in a box and instead just be open to the experience.
