Hera - sexy underwear, or some kind of outfit, always works a charm. My personal "thing" is fishnet stockings, the ones with the large, wide, holes. As for how you should act (if that's what you want to do)...well, what does he like? Sweet and innocent? Dirty and dominating? If he is like me, he will probably like a combination of both. If you want a more romantic night, a couple of candles and some incence in a darkened room works a charm. It's been done 1000 times before, but that's because it always works. Another turn on would be not to play any of the usual female games, or act coy, and so on (and in saying that, I hope I don't sound like a chauvinist). Just give it to him, let him have it. He will love you for it!
