So this girl I hooked up with once, we still talk and she was a good lay, so I'd like to make a FWB situation. Well she told me straight up before "You intrigue me, but I want someone else." If she was honest or not, I know this was a test. And honestly I'd rather have her intrigued than have her want me.

Intrigue makes her curious. She'll want more of me, and less of whoever she "wants." The question here is, any tips for creating more intrigue, or keeping that intrigue strong? So strong it makes her girlhood quiver.
