Am I wrong for wanting a virgin for my first time?

I think you have some misconceptions about women and sex. Many women don't feel "awe" the first time they have sex. There's nothing inherently magical or touching about losing your virginity, and having had sex in the past does NOT cheapen future sex. We women rarely orgasm the first time we have sex, and a lot of women have bad or so-so first times. Having more sexual experience makes it easier for us to orgasm, and often makes the sexual encounter better for everybody involved. A woman who knows her body will be able to teach you how to make her feel good.

Also, I'm not saying that YOU are sexist, but I think the whole notion of not wanting "to go where another man's been" is rooted in sexist notions of female purity. Having sex doesn't leave a taint on a woman or anything, and I don't think you'd be likely to hear a woman say that she doesn't want to go where another woman's been. I sympathise with your insecurity, but I don't think it's appropriate to insist that your girlfriend be a virgin. If the woman is reasonable, she'll understand that it's your first time, and she's not going to resent you for not knowing what you're doing. You have the right, of course, to choose whether or not to have sex with somebody, but I'm a bit torn, because telling a girl you don't want to have sex with her because she's not a virgin seems like a really awful thing to do.

Anyway, it's your choice, but I really think you should try to get over this insecurity. Our society places way too much value on women's virginity, and it can be really damaging to women.
