confused

So I met a guy and it's been three months that we've been together but officially yet.... I really like him and he likes me too but he hasn't asked out yet. We've been having sex and I'm scared that he is going to hurt me. I'm scared to tell him what I feel about him and I really want to have something serious with him! I'm so stressed and depressed! I don't know what to do ? 😩😩😩😩
