Lou, you are a woman after my own heart! and the sex scene with her and Antonio Banderas in Original Sin....purrrrrrrr yummmmmy mmmmmmhummmm!

I love the "love scene" with Wynona Rider and Gary Oldman in Brahm Stoker's Dracula. "take me away from all this...death."
Last but not least, and i know that i may come up with more later, is the bathtub scene in Queen of the Damned. Aaliyah slowly runs her hand up from water littered with red rose petals, up Stuart Townsends belly and chest. They share a smoldering hot kiss and then she goes down to bite his chest. That one is pretty much a guarantee for wet panties and a need for "an itch to be scratched"
