There's a girl who i'm not that interested in but i'm fairly sure she would be down to have sex..but how can I directly message her? I don't want to take her out waste my time. If she declines i don't care so it's a win / win situation. But what's the best way to approach this? Be super direct and ask her straight up? if so how would I word it? Should I just say h ey want to hang out and have some fun? ;) Or say want to get a grab a drink and have fun after? or just say want to have sex?

how do I go about this?
