LOL...
You're complaining about being in a room full of the oposite sex. If you were a guy in a class full of girls, you'd be one happy camper (or at least the average guy would be).
I'm a CIS major by the way, and in most my classes there are few, if any, females. I also like to do outdoor stuff (Camping, Hiking, Hunting, you get the idea), so I have a hard time making female friends, because it's hard to find common interests...
