In mainstream films, sex between two characters who are attracted to each other is almost always easy, once it occurs: everything gets hot and steamy and it's instant orgasms for all. The Big Easy (1987) is an exception.
New Orleans distric attorney Anne Osborn (Ellen Barkin) is falling in love with bad-boy cop Remy McSwain (Dennis Quaid), but when they go to bed together, the usual hot-and-steamy doesn't happen for her. She stops and says she's no good at sex, but he reaches down with his hand and changes her mind.
This scene still stands out among the millions of scenes of women instantly melting underneath men.
