Girls, I'm catching strong feelings for this guy. How do I know if he doesn't only want one thing?

He is tall, strong, confident, I feel like he can defend me physically, he changed the oil in my car once, and he fixed a hinge in my cupboard once. We've been on five dates and on the last one, we got a bit cosy on the couch while watching a movie. He put his arm around me and tickled my waist. I teased him by blocking the tv and stretching back so my shirt lifted. He reached out and tickled my belly and I backed way and stuck my tongue out at him. I came and sat next to him and watched the rest of the movie, he was calm about it. Should I have teased him like that?
