Please help. Am I overthinking?

So I just started dating (this is the second guy I've ever dated) and I've literally been on 3 dates with him and we've gotten pretty close but not hooked up. And like not emotionally or in conversation. He wasn't boring to talk to the first 2 times. And we weren't really talking a lot the 3rd time 😅

But I'm wondering if I'm worrying too much about whether I like him or not. I'm genuinely not sure how I'm supposed to feel or react to this stuff. I feel scared that I don't actually like him but this is also the first time I've let a guy get this close so isn't that a good sign? I do feel comfortable with him but it's not like I'm getting butterflies from just being with him. So yeah am I over thinking about having deep intense feelings? Is that something that develops or is just automatically there?
