It’s who she is with. How that person treats her out of the bedroom.
Get in touch with a woman emotionally, and you will get in touch with her physically
I understand and agree with you. And, believe it or not, I bought MIchele's "Sexless marriage" book and will read it after I finish both DR and DB books. I too lived with a woman for over 30 years who was mostly avoiding sex, and was so afraid of it after the first 10 years that she missed out on so much intimacy and romance because she was always afraid it would lead to sex.
But is Michele's conclusion that simple, that if only a husband was in touch with his wife emotionally, then everyone would be happy and satisfied? I'm not sure that's the case. Something to explore, certainly.
