Dirty Dancing isn't all that dirty. The dancers keep their clothes on… at least while they're dancing. Baby and Johnny do engage in a sexual relationship, during which we get an eyeful of Jennifer Grey's back and Patrick Swayze's side-butt (which is our new desktop wallpaper).
One issue parents might have is Baby's age—seventeen—and Johnny's age, unsaid. Swayze was eight years older than Jennifer Grey at time of filming. But, when discussing the issue of sexuality and virginity, it's important to examine how Baby's the one who takes control in this aspect of the relationship. He's an older man, her teacher and mentor, but he doesn't abuse this position in order to take advantage of her.
