That really is surprising. Maybe you're the intimidating kind of Latina. But, at the same time, how do you know they're not approaching *because* you're Latina? It could be a whole different reason. Your body language could be nervous or defensive. You could be saying "leave me alone, I don't want to talk to you" with your body language. Or, perhaps you live in a racist part. I think that's less likely, unless you live in Mississippi, Alabama or Tennessee or something. I live in Texas, and even here there's not much of that. Everyone gets along just fine, and everyone dates anyone.
Actually. Come to think of it, I've *mostly* dated Latinas. And I'm white. Almost all of my gfs have been Latina. Or half Latina or Hispanic/half white. Maybe half and half Latina and white. Or, perhaps you simply are either super hot, so guys are intimidated by your beauty--or just think such a hot girl would already be taken; or you're not very attractive and guys aren't interested (even if that's true, it's not the end of the world: guys will still approach even less than average girls eventually)
Though, according to various statistics, particularly okcupid statistics that I remember, people namely date within their own race. They prefer their own race, naturally. The familiar, the known. So it might just be that they're after the white chicks. I would be curious what the racial demographic is at your college. Is it mostly white people? If it's in the U. S., then probably, given we're 76% of the population. In that case, they might just feel more comfortable around their own race. But like I said, it could also be how you carry yourself. How friendly you are, if you go off into the corner of the room or cross your arms a lot or avoid eye contact and stuff. Usually, a guy has to know that there's some kind of chance. A certain kind of eye contact can do that and let him know that you're interested--or at least give him an idea that it's possible.
