My line of thinking is if a guy wants to screw me, then he better be offering up something in return. This is a personal choice because of the fact that I'm not an easy-to-get-off girl. I enjoy sex anyway, but not to its fullest advantage. More often than not these guys are mediocre to terrible lays because they're incredibly selfish. They start to get frustrated when I don't get off in 10 minutes after they start humping. I don't blame theme entirely. They have a lot of preconceived notions about sex that just aren't true. Most of it they've learned from porn or girlfriends who pretended these guys were the best lays in history just to save their egos.
I don't take advantage of my guy friends. I'm perfectly happy to exchange massages with them, or hang out with them, pay for dinner or split the bill. What I meant was that I can often have a better, fulfilling friendship with a platonic guy friend than I can have with a FWB. FWB is a deal, an arrangement. Remember when I said I separate my FWB from my platonic friends? If a platonic friend of mine decided he wanted to jump by bones and got the courage to do it, the relationship would then change and I would never be able to treat him like a platonic buddy anymore. Sex changes things for me. Either a guy can be comfortable with how I handle that, or he can find someone who can give him what he really wants.
