When I first got out of a long term relationship a few months ago, I felt a lot like how you described.
I went out with some friends, and everyone was doing the whole looking at each other accross the bar, flirting, making the first moves, getting drunk etc. and I thought "this isn't for me. I can't be bothered with the initial stages, I don't have the energy it requires to meet someone new, cant deal with the worry of rejection, finding out all about someone, it seems like too much hassle" ...yet I was lonely, and I guess what I really wanted was to date my best male friend, who wasn't interested. :-s
In the end, I met people in other ways, and they were friends before I looked at them as possible love interests, which is always a good way to start :-)
I do generally enjoy the thrill of the chase, but I know people who don't. I also know people who like the flirting, but don't like to follow it up with anything sexual. We're all different.
Also, if you don't feel compelled beyong reistance to be with someone, chances are the feelings arent that strong, and they aren't a good bet to date anyway, Im sure you know when you really fall for someone, you'd do anything to be with them :-) You can't just date someone because they are interested in you.
Dont worry too much, and hope you sort this out
