How do I explain to the guy that I’m seeing that what we have is more than physical?

He says he only wants a physical relationship. Though he doesn’t want me to see any other guy. We do more then have sex. Go out on dates. We only see each other once or twice a week but talk everyday. He always wants to cuddle and be close to me. He kisses me goodbye multiple. I say we are casually dating. I think of just physical relationship as having sex and leaving. Not spending any other time with that person and definitely no cuddling
