The opening scene in Chicago. But mostly because of the musical number. It sets the scene for the entire film very well.

I also like the scenes in the Secretary! My favorite non-porn movie with great scenes that I find incredibly erotic is 9 1/2 weeks...gets my juices flowing every time I see it. It is older, though, from 1986, so I can't wait to see the responses to this question to see what current movies are out there.

I'll agree with Secretary. I wasn't sure how my wife would enjoy it, but she definitely did. And then she surprised me after we watched it.

I completely agree with everyone about The Secretary. I also found the speed dating scene in 40 yr old virgin where the woman's top slips to the side slowly and her breast is exposed to be super erotic.

Oh, and the frisking scene in Taxi (the movie with Queen Latifah and Jimmy Fallon) is also pretty erotic.

Another n+1 for the move secretary. I haven't seen black Swan but the clips of the sex scene I saw on fleshbot where hot. Also the sex scenes in the movie Chloe. I could probably think of more but those are the ones that came to mind.

There's a long girl/girl make out scene in the movie Bitch Slap (which is pretty horrible) that was super hot and even led to real life sex.

Cruel Intentions. Yummy.

Going waaaaay back to 1939, I believe, is The Lady Eve. Henry Fonda is a herpetologist and the heir to a beer brewing fortune taking a cruise on his way back from a year in the jungle collecting snakes. Gorgeous and stylish Barbara Stanwyck is a hard-boiled, soft-hearted "adventuress" on the same cruise, sizing up the passengers for her next con -- who ends up being the handsome and naive Fonda.

Stanwyck arranges for Fonda to "accidentally" trip her and turn her ankle. He, being the gallant, volunteers to help Barbara Stanwyck back to her room. He helps her to a chair and he kneels at her feet, awkwardly yet delicately assisting her with buckling her shoe, all nervous big hands and earnestness. She confidently perches on the chair, above him, slender calf and foot offered to him while talking in a calculated breathy bedroom voice. Gradually we see her put-on attraction shift to genuine attraction. Kapow! The chemistry in that scene! Golly!

I've always loved 9 1/2 Weeks! It is the best R rated erotic movie I've ever seen.

The scene between Susan Serandon and Kathering DeNueve (sp?) in the Hunger.

Selma Hayek in "From Dusk til Dawn". They are in the bar and she's the dancing entertainment! Very HOT!

Erotic sex scenes from TV shows I have watched in the past:

The scene in the falling building between Buffy and Spike.

Almost any sex scene with Shane from The "L" Word!

I love 'I'll Cover You' from RENT. Also, 'Point of No Return' in Phantom of the Opera.

I've heard people call the TV show The Tudors made for TV porn.. but I guess I'd have to say it was when two characters were having sex after having been on a boat for weeks, his and her moans and orgasming souns seems so real and I can just about get off on the sound alone without watching the scene.

This is an easy question. By far, TRUE BLOOD. It is on HBO and VERY HOT!!!
