How to know when I'm ready.

I was just on a first date with a guy this weekend. There were a couple things that made me uncomfortable on the date that I'm trying to look past and give him a chance for a second one. Nothing big, just that he was a little too huggy, he complemented me a lot, and he did arrive late to the date(I will be watching the clock on the second one to see if this is a pattern). At the end of the date, he stared into my eyes and asked to kiss me on the cheek. I let him. Now onto the issue, I'm 22 going on 23 in February. I have never had my first kiss and this may sound super stupid, but how do I know when is the right time? How do I know when I am ready? Like I think probably the reason he asked to kiss me on the cheek is cause he could see the fear in my eyes and it was only a first date. I think I'm so afraid because I've built it up and built it up in my head and now, at my age, I want it to be with the RIGHT person. So really how do I know?
