The ones I know are platonic, alterous, romantic, sexual, aesthetic, and sensual. There are probably more.
Platonic: I want to be friends with you
Alterous: I want to be friends with you or date you? Either is cool?
Romantic: I want to date you
Sexual: I want to sleep with you
Aesthetic: Wow that's pretty
Sensual: I want to hug you
As I said, there are almost certainly more!
Personally as an ace I Do Not Understand sexual attraction. Whenever my friends start talking about it I just sit there going "?!! What?!!!". My family automatically assumes anyone who doesn't want to sleep with people is a nun, which is wrong on so many levels. So that's fun
@Ruku Welcome to the Shard, fellow questioning trans person!!!!! Good luck figuring out your gender!!! (That is not supposed to sound sarcastic; I'm just terrible at tone)
