And just remember, if it feels forced, it's probably not going to work out in the long run. Sure you'll never even know if you don't start out as friends, but if you two get along and have chemistry and all the shit that's actually important in a relationship, you'll know it that way and asking her out should be easy. If it turns out she's really hot but has no personality or is a bitch or some stupid shit like that, don't just ignore it and get with her for her looks, unless you and her both know it's going to be a one-time, fuck-her-and-leave-her type deal. Otherwise you'll just end up not having a good time.
I tried going out with a girl "just because" once; it didn't work. At all.
