There was a movie on cinemax after dark about a woman who is a radio host during the night. She hears peoples stories sex. No it is not the best sex ever series. The radio host is being stalked. One scene I remember is her at home masturbating to a fan letter the getting done and finding an envolope on a table beside her couch. In side the envolope are pictures of her masturbating just now. I need to find the name of this movie and the name of the actress who is the radio host in the movie.

Sounds like Sinful Desires (2002) (V) (http://www.imdb.com/title/tt0403505/)
