"Place conditioning" is experienced by heroin users, and is a phenomenon in which they get less of a high if they self-administer the dragon in the ame physical location for very long. Now, mentally combine this with "Stockholm Syndrome" in a gedachen experiment. These two appear to be simultaneously present in many relationships.
A remedy might include : 1) freeing onessself from their captor; and 2) having intimacy in a location other than the usual place. But compounding the difficulty is that the "captor" is the one with whom intimacy is experienced. If the "freeing" could be done internally from the mental perspective, then the issues reduce to then only a change of venue for intimacy, and that change itself need not necessarily be physical, provided one can create the appearance of s new venue in the minds of both. Many achieve this unknowingly via fantasy role-playing / scenarios, toys. I could expound further but at present only have one hand to type with and I probably gave ya a little here to mull over. Those who can't get out of these two simultaneous syndromes are destined to experience neuroses to some degree, which can easily grow fractally into other aspects of the existence, if permitted to continue.
