I got nervous about this before I started dating.
I talked online with my current partner for about 2 months before we met, and then I insisted that we go to an arcade to play pool and air hockey, because I didn't want to sit through any uncomfortable silences. It turned out that there weren't any, because we clicked really easily. So my fears on that occasion were for nothing.
Another date I went on, I went out to a bar and talked with the guy. It ended up being really painful, and I wanted to cut it short, but wasn't smart enough to do that. I would now. After the date, I realized that there was absolutely no way I could see myself with that guy, as talking is something that has to come easy.
So the upshot of what I'm saying is, don't worry about dating. If you go on a date and it doesn't feel easy, then cut it short and realize that he's not the one (or one of the ones) for you. Be comfortable with yourself. If you want to make out with the guy on the first date, or second date, or whatever, let him know that you like him and that you'd like to kiss him. If he wants to kiss you and you're not into it, tell him you're not ready yet. The same goes for everything else (including sex).
You could also do what Trocks did and create a thread about it and get advice/suggestions from everyone as you date. Just make sure you update it when you say you're going to
