always so paranoid

Today I went on a second date with a guy that I met off of Eharmony. It went great; we ended up spending 7 hours together, and it flew by. We went to a bar, walked around town, then went back to his apartment and watched a movie/tv. I couldn't believe how late it had gotten.

While we were hanging out, he told me on two separate occasions that he'd like to hangout more often, and he asked about my work schedule for this week. And before I left, he told me he really likes hanging out with me, and I said I liked hanging out alot too.

I really do enjoy myself around him, it's weird to finally meet someone that I actually have alot in common with. I don't feel uncomfortable around him, or awkward. We never run out of things to talk about.

But for some reason, I'm still worried in the back of my head that I'm going to say or do something wrong and totally blow it. For example, the first time we hung out, I hugged him before I left. Tonight however, I was too busy worrying about the homework I had to do when I got home that I forgot to hug him. On my way to my car I realized I had forgot to and I was like damnit.

Besides forgetting to hug him, our time together was awesome. It was hard to resist getting close to him on the couch, but I controlled myself

I guess the point of this rambling post is to ask if there's any way I can make myself less paranoid that I'm going to screw things up?

In answer to your basic question of how to be less paranoid, as has already been mentioned, relax.

Now a few observations on your post that you really did not ask about.
1. You forgot to hug him because you were worrying about homework. If you are going on a date then you need to be able to focus on your date. If there are other things in your life that are occupying your mind such that you are not 100% with your date then you should not go on that date. Wait until you can be "all there".
2. YOU forgot to hug him goodbye. What was HE doing that he could not have initiated the hug?
3. You hugged him on the first date but not on the second. In my own paranoid mind I am going to read that as "she is not that interested". No reason to ask for a third date. In other words with me you would have already blown it.
4. Just an aside but in my experience when just beginning to date someone when the dates are lasting a long time (7 hours) things don't work out in the long run.
