What do you know! A sex vid that really, truly is designed to inform and educate! If only they'd shown you stuff like this in sex ed - the world would be such a happy, cum-drenched place. Hosted by the cheery Dr. Carol Queen, who says she's the staff sexologist at Good Vibrations, this vid basically is an everything-you-need-to-know tutorial on the G-spot, complete with an anatomy lesson, tips for finding it, the history of its discovery, safe sex instruction and plenty of explicit demonstration footage.

A couple of the more interesting points made here are that a woman's arousal level is key to her being able to locate her G-spot - unless she's good and hot, she probably won't, Dr. Queen says - and that nobody really knows where female ejaculate comes from. Be that as it may, there are women in the demonstration scenes who expunge buckets of it, leaving enormous pools on the sheets beneath them.

Though the vid seems slightly aimed in the direction of the lesbian crowd, it's a highly valuable teaching tool for women of any orientation, as well as their partners.
