Be patient looking for a game here. Listings in the game finder can be stale so don't get discouraged. You won't get replies from lots of DMs. Don't get discouraged. People will no-show for your first game. Don't get discouraged. You *will* find a fun group if you keep at it but, like dating, it's kind of a numbers game. Don't think of the failures as rejections and keep on asking people out on new dates. :D While it's helpful to have a character concept running around in your head, most DMs aren't going to be judging your application based on your character. They are more interested in what kind of player you are going to be and what you are looking for, how you'll work with a group, etc. Make sure you tell them about you and what you want to get out of the game. What your play style might be like, etc. I know that can be tricky since you're a virgin, but try to think about it. Paid games are easier to get into. If you have a budget, I'm playing with a paid DM now who's quite awesome and has some openings in some of his games still, I think. You can send me a DM if you want his contact info. There are also plenty of paid games in the game finder, though I never got a response from any of those DMs ironically.
