I'm pretty sure this movie is an '80s film but could possibly have been '70s.

The film featured a record that, when played, the music would get the characters aroused and have sex. I also remember a blond (I think she was the main character) who would always tell the guys "Be gentle" when they'd start going at it. I also remember her wearing red/white striped knee socks.

I'll edit this post if I remember any more details, but does this sound familiar to anybody here?
