Turtles

So, for a while I've identified as Pansexual and Genderfluid but I'm in a relationship rn and I think I only like him platonically because he kissed me, and I felt like throwing up. Idk if this is normal but I've never understood the concept of romance or sex and honestly it kinda grosses me out. I just wanna find out if I'm Aro/Ace or not and all of my friends are telling me to look into it so here I am. Please help!!!
