Query: do NOT trust these authors

A family doctor recommended this book and also referred me to see Stephen E. Lamb, one of the authors. I purchased the book, and I visited him twice. Both visits were a couple of the worst experiences of my life. I would not recommend his Doctor's office or his advice to anyone. The office staff was extremely rude, and Dr. Lamb's advice was completely insensitive and uneducated (my husband agrees). I left his office in tears on both occasions. He basically told me that if I didn't start "putting out" my husband would need to find other avenues for sex. I threw the book out as I would not want anyone else to be misguided.
