An excellent primer for those who are inexperienced. Learned a few things myself. Personally didn't agree with some of the info in the Health and other issues chapters but it is easy to skip these. No photos - just drawings.
Very informative about the technicalities, and inclusive of quite a bit of "ideas" and "niceties" to add some spice. Extremely professional illustrations - no photographs, only drawings. Highly appropriate for any married or engaged couple, or a high school or college level sex ed course. See also "More Joy of Sex"!!
