I say do the sex thing - but very very well That should do it! But seriously, have the sex! The way I see it, that's what I want right now, and when a guy wants it and I want it, good.
But, the minute the guy only wants the sex, the girls seem to immediately want more than just the sex. At least that's my experience with men. I have the sex, and if I likey enough to want to explore further, then he's not interested.
Allways remember ... lust will never hurt your feelings
