The scene I'm about to show you is not smexxxy...but it is hilarious in its attempt to be smexxxy. It's from the movie "Just Friends" starring Ryan Reynolds, Amy Smart, and Anna Faris.
The movie is about a fat kid who develops a crush for the popular girl at school and then becomes a success in L.A. and comes back to win her love. Hilarity ensues (of course) in his efforts to impress her. It's a romantic comedy for guys.
Anyway, in this scene they have just finished a horrible first date and the guy is taking her home. After literally dry humping her on her front stoop he walks back to his car and freaks out.
