Am I wrong? Don't guys want women to dress and tease like this? Don't you dream about this shit? All the time? So, when she does it—entirely for your pleasure, BTW—why do you call her a whore? WTF? 

When my girlfriend meets me like this, I'd never ever do anything to discourage her from doing it again. When you say things like, "Oh baby, you look so good. You're so sexy!" And then bang her like a screen door in a hurricane, you can almost be certain she'll do it for you again. And isn't that what you want? Dudes: Don't be a dick!
