I friend zone girls. Most terms and dynamics in seduction go both ways, including this concept.
I met a girl at a party and thought she was cute, and I made the mistake of asking one of her friends to be my beer pong partner instead of her. The cute girl and her friend ended up ditching this girl and taking off, so she was stuck there and it ended up being obvious she was into me, so I got the digits anyway in the hopes of hanging out with her and seeing the better looking girl again. I've heard through the grapevine that she wants my nuts (if it wasn't already obvious), but she's not the one I want. Basically, I want to fvck her friend, so I'm going to have to find a way to just hang out with all of them in a group. That coupled with the fact that this week is finals week and then summer break, so there's a good chance none of this will go anywhere. It doesn't even matter that much, but if you've read this lame paragraph props to you.
I also have a female friend I'm not into sexually, but I could always tell she wanted me. She had a long-distance boyfriend for most of this time, though, so I was relatively safe. They broke up recently, and she's made it fairly obvious she wants me to fvck her, but I just shut her down. We still hang out though sometimes.
