Is it wrong to have sex with him?

I'm talking to this guy I met I tinder(don't judge) and I really like him. We are so comfortable with each other and he's a really sweet guy. As for now we're just friends, but we talk about our past relationships, and what we like and don't like. I'm honestly not sure if he likes me, or just wants to be friends:/ but I'm starting to like him because of how comfortable he makes me feel.
