More for education than strictly for pleasure, Victoria Zdrock's Guide to Great Sex impresses us nonetheless. With couplings such as Randy Spears and Sienna Miller, Steven St. Croix and Angelina Ashe and more, it's hard not to appreciate the action on the screen.

Even more impressive, however, are the no-nonsense and non-threatening tips offered by Dr. Victoria Zdrock, who has penned a sex advice column for Penthouse for a number of years now. Though some of the tips come in the middle of scenes, complete with written versions superimposed on the screwing, they are presented during position changes, in an effort to be less intrusive. And the bonus is the tips are actually helpful, from how to wear a cock ring, to what positions work best for various penis sizes.

Boosting the value of this disc even more is a bonus scene from another instructional vid, AdultFriendFinder.com's Guide to Threesomes.
