3 weeks too soon?

Hi! I’ve been dating someone for 3 weeks and I struggle with anxious attachment (will make sense later). I really like him and we’ve been on 3 dates: one couple hour coffee date, one talking over drinks that lead to making out and me inviting him over and one at my house making dinner where he slept over and stayed till 1pm the next day (17.5 hours together). I really like him…. I’ve been trying to date other people because I struggle from anxious attachment and I feel this would help me. I feel guilty about the dates and I don’t really want to date other people at this point. But I feel I should if he wants to keep it slow and casual. He invited me to his choir performance and I’m going and then we have plans the next day. We do not text very often at all but he also doesn’t have a smart phone and I think this is good for my anxious attachment. Is it too soon to ask him what he wants? Or if he wants to be exclusive? He also told me he hadn’t had sex for 2 years before me (not sure about anything else intimate though). Thank you for your help!!!!
