Are *ALL* These Nina DVD's almost identical copies???!!I liked the cover... looks very nice although it appears photoshopped... Cannot honestly find much more to be enjoyed or learned from this 2 hour session of nauseating intercourse between a 50-55 year old Nina Hartley and some much younger plain jane woman thabkfully without deep wrinkles, engaging in a highly unappealing lesbian encounter. The rest, is mainly yadda-yadda-yadda, with more talk still, and a session with a much younger man that does'nt teach anything that you don't already know from common sense, with a few clinical details about clitoral and birth canal sensitivity, and that is really pretty much it. Nothing you could'nt find good info about on the net for FREE. So if you like Nina Hartley, here's your opportunity for 2 grueling hours of a very boring lecture... truly mostly all talk, and highly unattractive and obviously unpleasant "routine sex" demonstration, then this is *definitely* for you...
