I dont have any romantic feelings

I've been thinking i'm aromantic for a while but im still not sure since i'm pretty young. I love making out with guys but just for fun and in terms of sex.
When it comes to an actual relationship im just not interested.
I never liked dates but i tried last week with this guy that is seriously sweet, fun and we have a lot of things in common. We kissed several times but i didn't feel anything even though he is not a bad kisser. Its cool to hang out with him but i just dont feel something special at least not as he feels for me.
