Here's a collection of rear-view images that are SFW. Some are quite fetching!
A photograph taken from an unusual angle can take an image from the dull to the wonderful in an instant. Instead of concentrating on the face, why not take a chance on that sometimes neglected (and other times overused) part of the anatomy - the butt. Call it what you like, caboose, bum or bottom - its inclusion on film can make a photograph. Have a look at this collection - no ifs or ands, but quite a few butts.
