As lycanthrope said, most men don't even need to be seduced... just given the opportunity Seduction has an attraction though. You still don't give an answer of what you gain from this and you haven't mentioned the consequences for the man if he truly doesn't want sex outside marriage. I suspect he'd bounce back from that little indiscretion though. Try Lycanthrope's suggestion although from what you've said I'd imagine the guy has picked up on your signals already. Maybe he wants to see how hard you'd try. Maybe he wants to be seduced and that will give him a rationalization for his "sin." Maybe he just doesn't want you. I'm from a large city in the west and maybe I just don't get your culture and that could matter.
There are certain things that I suppose are universal. You have to get him alone. Ask him to help you with something. You have to get close... close enough to invade his personal space. Close enough to feel your heat and catch your scent. Touch his face, hair, throat, but only enough to notice. Take his hand and lightly caress the palm with your thumb. Look into his eyes. Take his hand and lead him on and stop suddenly so that he's touching you. Look back at him. Hold his gaze. If he doesn't give you the response you're looking for then... try Lycanthrope's suggestion but be prepared for a no because he doesn't want it and it isn't going to happen.
I apologize to the forum if I said anything you find inappropriate. I've seen stranger questions and answers here.
