Don't let people to make a profit from this nonsense. You have a better way to find a girlfriend/boyfriend. Go out more often. If you do that, you will find more friends and friends leads to more friends. Some of them will be girls/boys, but if you are not capable to find some friends, how the hell girlfriend/boyfriend will like you? It's the same thing. If you don't like going out, why not? It's fun, you just need to meet right people, whom you like.
Be confident about yourself, because we all aren't perfect, and if you fail at something, it doesn't matter. Just talk, relax, be yourself and don't worry.
The only thing makes it worthy to go in those sites is when you are looking something none traditional, like bdsm or other perversion. Because in real life I think you would be kind of ashamed to tell someone you don't know very well, and if you already became a couple, she might still don't want to do it in your way.
