As a man living in a college town, I see lots of young, attractive women every day. When on a date with a girl I have to make an effort to not check out other girls I see because I've always heard that's a big turnoff. So I have to curb my instinct to check out other girls. (Though I suppose RP types might argue that flirting with other girls would establish higher value.)

I'm curious, do women have a similar challenge?
