one night stands

Have casual sex with random people? Especially having sex with someone you may never see again and all you know about them is their first name(if they didn't lie to you). I can understand the thrill of meeting someone at the store, club, or whatever.. exchange numbers and smash that same night...

What's the difference ladies? Especially if they are both equal in terms of looks? What deems a guy relationship material versus one that isn't in your eyes ladies? Is the one you fukking immediately getting sexual and making it known he wants to fukk right from the get go? Don't wanna be...
