Whenever I'm single (which is unfortunately true right now...) I tend to develop small crushes on practically every decent looking/nice guy I meet or come in contact with. I don't mean that I want to date every one of these guys and I'm far from being an excessive flirt. I'm just wondering whether or not this is normal. Do any of you guys, especially when you're single, form small crushes on almost every attractive female you come across?
Oh, and this is just another question I thought of. I've heard, from a few of my guy friends that when a girl walks into a room, the first thing a guy thinks is whether or not she's "do-able," their words, not mine. Is this true as well?
