This is the third of a four part series of Stan Tatkin's new book, We Do: Saying Yes to a Relationship of Depth, True Connection, and Enduring Love. This portion involves how Tatkin addresses sexuality, substance use, and infidelity. A special thanks goes to Peter Jones, EdD for writing this series.

In We Do, sex, with its intensity of contact and proximity, is presented as a potential psychobiological minefield, fueling the troublesome triad of communication, perception and memory. Because “in the psychobiological world partners repeat the same mistakes everywhere, regardless of the situation,” what goes wrong in sex is predictable from trouble in other areas.
