The Intendant in the mirror universe in Deep Space 9 made my jaw drop. I never looked at Kira the same again. 
I can’t find any good YouTube clips, unfortunately.
Most of the scenes in Unfaithful, but, especially the one where Diane Lane’s things and stomach are all aquiver!
I give her a pass on that, because first off she’s tiny and a snake that size is VERY heavy and secondly she is absolutely terrified of snakes but did the scene anyway. What a trouper!
She had some pretty nice scenes with Colin Farrell in “Ask The Dust.” She has a bottom you could bounce quarters off!
Yeah, bounce that quarter…get back a dime, two nickels, and five pennies. 
Sometimes she looks pretty hot; other times not so much. Penelope Cruz on the other hand…
You like naked girls and snakes?
Or this one, which caused quite a stir at the time…
Joan Chen with Anne Heche in Wild Side
And while it’s not my cup of tea, in the same film there’s Christopher Walken with Steven Bauer.
James Woods burning Debbie Harry’s breast with a cigarette, in Videodrome, did it for me.
I’m not sure how long she would tolerate it for, though. 
Scenes of women with badgers or mushrooms just don’t have the same appeal.
Ooh, yeah. I’ve seen that clip… very steamy.
Heath Ledger and Jake Gyllenhall in the tent in Brokeback Mountain.
Heath and Jake in the alley outside Heath’s house in the same film.
Most of Sex and Lucia.
Two words: Paz Vega!
The end of “Sunshine” is hot indeed.
Seriously…one need look no further than Mulholland Dr.
All of the scenes with Jennifer Connelly in Hot Spot.
Yowzaaaa…
This woke me up from my Monday morning slumber - good 
Bridget Fonda and Dermot Mulroney in Point of No Return, the ravioli scene.
The threesome scene from The Last Emperor and speaking of Bertolucci, The Dreamers has several hot scenes.
Anne Hathaway trying to seduce the camera geek in Havoc made me… uh…
I’ll be right back.
Michelle Pfeiffer. In that dress. On a piano. In the Fabulous Baker Boys.
Brad Pitt’s seduction of Geena Davis in Thelma and Louise.
