If someone has intimacy issues after 5 years, he/she may want to consider seeing a relationship therapist instead of buying a self-published book from some guy on the internet that tells you how to pick up women in a bar.

Regardless of that, the book is not about managing long-term relationships. Ostensibly, it's about how to get relationships started in the first place. Therefore, whether a given interaction may or may not be appropriate with a girlfriend of 5 years is irrelevant to the conversation. That was my point.

Becoming a better seductor is only a small subset of being receptive to your partner's needs and actually caring about them. There's a lot more to a successful relationship than sex and seduction, and the idea of no divorces if everyone started having better sex is laughable.
