This is a personal favorite as gifts to friends for the innocent illustrations.  Each card has the position on one side and the back explains: how to achieve, why it's good for men, why it's good for women, cautions and variations.

 

Examples of the positions are:

On the Edge

Discreet Doggie

Stargazer

Reverse Cowgirl
