This excellent instructional video featuring sex education guru Carol Queen is a must-have for heterosexual couples interested in exploring anal sex.
Though it is more geared towards women pleasuring men using dildos and strap-ons, the information discussed would be helpful to anyone new to anal play. Two couples join Carol and her partner Robert Morgan in this light and down-to-earth discussion and demonstration video.
If you're looking for a video that provides a pornographic turn-on, this isn't really that sort of production. From an educational/informational standpoint, however, it gets our top rating.
