Hey, Matt. First of all, honey, the more desperate you seem, the faster we run. You need just to be yourself (especially if that's a caring, loving, kind, funny, non-selfish young man.)! But if you want a girlfriend just for the sake of having a girlfriend or for physical reasons, then I wouldn't expect it to happen soon because, most of the time, it can be spotted. Just be a good guy and see what happens. It'll all work out. :-)
You could buy one... but other than that.... You go out and meet people. Introduce yourself. Let them meet you and get to know you. If someone takes a liking to you then you can possibly start a relationship. The latter is probably the better way to go.
