A couple new ones...

Lost and Delirious (2001) with Piper Perabo - she and Jessica Pare' have fun with each other in an all girl boarding school while her roommate watches... very erotic!

Body Shots (1999) - Emma and Shawn find themselves alone outside near a car and after making out, he goes down on her and she returns the favor - they end up going at it up against the fence in the alley and they end with him holding a used condom in his hand - it's very realistic and erotic - very raw!
