The Sexy Vampire challenge

Why do almost all vampires in the last few years have to have a sexually hedonistic lifestyle? Yes, yes, I know the modern vampire myths contain a lot of sexual tension but I would love to see one where the vampire in question sits back and doesn't engage in all the flirting and sex. Not that he doesn't want to. He knows that he can get a little action when he wants it. It's just that he doesn't feel the need to indulge to prove his own prowess. Same thing with a female vampire.

I'd like to see something subtle, understated.

Oh, I have no problems with the vampiric allure being partially or even mostly about the sexual. I want something more.... sensual. And I'm not looking for understated than I am for not having the vamp walking into the room and all the members of the opposite sex (and even some of the same sex) start throwing themselves at him or her for a romp between the sheets. I want it where people know s/he walks into the room but are able to keep their clothes on.

And yeah, I know there are examples, like the series The Kindred where the Prince of the City had people always keeping part of their attention on what he's doing when he's in the room but not a harem ready to strip nekkid at the first sign of interest. Yes, he was a handsome man but as much of his power came from him being a well-known and well-connected business man as the sexual allurement of him being a vampire. It's not that women weren't interested. More that there was more to his attractiveness than just sex.
