I have only just discovered this illustrated 400 page guide. Although it came out in 2001, it is bang up to date on relationships, fetishes, cross-gender issues, gay & lesbian sex etc. etc. She must have been ahead of her time when she wrote it! Covers just about every aspect of sex you can imagine, & many I had never heard of. Refreshingly non-judgemental, tolerant of varied attitudes to sex. As you would expect from a sex therapist there is quite a lot about emotional aspects of sex, very liberating stuff!
