How soon after meeting someone do you get physical?

Ok so, I met this really attractive and sweet guy a couple weeks ago online. We’ve been out on two dates. We haven’t gotten physical at all, not even hugging or holding hands. After our second date, he texted me and asked me if it was ok for him to hug me next time he sees me and that he didn’t want to cross boundaries or make me uncomfortable. I thought that was so sweet! Anyways, I feel like I am soooo awkward, it’s hard for me to get intimate with someone for the first time unless I’m like, drunk. I know that sounds bad but it just takes me awhile to get that comfortable around someone. I feel like a little kid. I’m scared to hold his hand, kiss him, Etc. It just freaks me out and makes me nervous. Any experiences or suggestions?!
