I'm 18 and never had a boyfriend but this guy asked me out???

I have just finished my first year in college and I'm 18 and I have never had a boyfriend. Mostly It was because I was extremely shy in high school. However, in college I started to open up more and I am not so shy anymore. I started talking to this guy at my college and we started to become good friends, he asked me out to eat, and a movie so I think he is interested. So, do you think he will be weirded out by the fact that I never even had a boyfriend? He's had a few girlfriends. Sometimes I think that I am just worrying about it too much, but Im 18 and have not even kissed a guy! Any advice? When do you think he will ask how many relationships have I had?? ( on the first date, or midway through the relationship?)
