This set of DVD's is worth getting for a start to finish exploration of all aspects of intimacy and sex. The models are on the whole great and the commentary is informative and very educational. Most of it is obvious but its definitely better to see and hear it while a couple watch it together, trying out some of the tips and positions, etc. Not using porn star's with plastic implants and 9 inch penises worked for us as it's way more realistic and intimate. One criticism would be that most of this was filmed years ago, would have been much better to have a similar version but much more recent as some of the ideas about sex, positions and techniques have changed over the years. On the whole, we enjoyed it and are already applying some of the advice with electrifying results! Thanks.
