Hi, Misery, welcome to PsychCentral (PC). I was like that, went to the University of Maryland (graduated in 1972 :-)

When you say you don't want to lower your standards, what are you thinking/imagining? How are your standards different from what you see around you? What sort of guy attracts you? Do you ever suggest doing something with one of them, let them know at all you're interested? You may be perceived as not interested, because you're less vocal or something.

I'd set up a test of some sort. Think of some activity in the future and at a party before then, if you meet someone you might like, ask them are they going to that activity or could you tag along with they and their friends, etc. Do you have some girlfriends who have boyfriends? Maybe someone could set you up with someone? Think of a couple simple ways you could get invited to something (instead of just going on your own?).

I wouldn't worry about your Self, relationships take practice like anything else. If you haven't had practice, you're not going to be great at it right out of the box? You have to learn and get comfortable with it is all. You have all the "equipment" I imagine, there's nothing wrong with you. Figure out a plan to get some experience and, over time, it will get easier.
