Hot Oil / Lotion DVDs?

[Oil]

One type of sex scene that I've never scene in U.S. DVD releases has been those involving Oil or Lotion (where the gal gets all "oily" / "shiny" :). Why is this? I guess it's not that big of a fetish or in thing perhaps (I dig gals all sun-tanned out w/ that suntan lotion / oil look :).

* Can anyone recommend any good DVDs w/ good "Oil Sex Scenes"?

Thanx~
