Books on the psychology of intimacy seem somewhat irrelevant when there are conditions such as Post Orgasmic Illness Syndrome that are completely unknown to the medical community. How can one even begin to discern the psychology of sex when there is physiological conditions resulting from a simple orgasm that almost no doctors or researchers have any answers for? To me it seems similar to diagnosing someone with schizophrenia as "being possessed with spirits" instead, when in reality the schizophrenia is leaving holes in their brain that can be observed under a microscope.
So you have millions of couples who have sex, and any number of them could have POIS on some level, that affects their cognitive and emotional state on a physiological level, but the modern medical community has skipped over the reality of this physiological condition for the length of medical history. You have some reference based in ages old spiritual theology. Some monk, somewhere, realized that some feel negative effects after orgasm, but without the education of modern science, attributed it to some metaphysical condition.
This really pisses me off. Seriously. How medically advanced can we be when one of the most common physiological interactions between a women and man who are intimate is little understood physiologically? Instead billions are poured into "erectile dysfunction" medications. Hey, you got to research where the money is, right? Gotta love that.
I do apologize, but without anyone clearly understanding POIS, or the causes, or having the ability to measure its level of severity in a human being, I believe any psychological interpretation of the physiological neurological effects that occur after sex in human beings is relatively irrelevant and cannot be accepted as accurate.
As a sufferer of severe POIS, this is just my opinion, and of course it is probably jaded by the fact that after decades and billions of dollars, there isnt a doctor in the world who really has a clue about how to properly treat or cure this condition.
