There appears to be some reason to question this conclusion. Taken from another thread:
According to the article "Husband-wife Similarity in Response to Erotic Stimuli" (Journal of Personality, Vol. 43, Issue 3, p. 385-394), those with more restrictive, more negative, and more authoritarian views of sexuality are more aroused by pornographic stimuli. The article "Sexual Guilt and Religion" (The Family Coordinator, Vol. 28, Issue 3, p. 353-357) discusses a study showing that while sexual guilt is more influential than religion in predicting sexual attitudes and behavior, "the more frequently [people] attend church, the more likely they are to have high sexual guilt which interferes with their sexuality." In other words, religion can lead to sexual guilt, and sexual guilt can lead to unhealthy sexual behaviors such as compulsive masturbating and porn use.
I won't even go into here, because of some present time constraints, the severe problems of using two obscure studies by personality theorists (let us not mince words when we mention that clinical psychology is a highly philosophical and plastic discipline easily molded to coincide with fashionable intellectual trends within the larger society, and has been bent to such ends for generations) while ignoring other data available that may tend to confute such claims. There is social science material to the contrary, you know.
This is so typically Liberal as to be both hysterical and numbingly predictable at the same time. Only a true, dyed in the wool social Leftist would make the claim that serious moral self discipline and moral imagination with regard to the proper exercise and use of our sexuality actually produces social and psychological pathology, as opposed to the rather pedestrian observation well backed by several generations of cultural experience, that it is the unrestrained expression of sexuality,
deracinated of religiously grounded controls and demarcation lines, that creates both personal and social pathology as well as sexual dissatisfaction, which there is research to show is, overall, higher in healthy marriages than outside of that institution. In other words, church attendance doesn't increase the likelihood of compulsive masturbation and indulgence in pornography (as if Liberals are, in general, against that), but indulgence in masturbation and pornography increase the likelihood that such things will--well, be indulged in, and increases the likelihood that they will become pathological (and the prevelance of sexual addiction in modern western countries, especially the United States, is not indicative of church attendance (this idea is counterintuitive at very best, and has no precedent in any serious major social science study I am aware of. I say "serious" because social science has been wrong on so many occasions on so many issues that, admittedly, we could quote all the journal articles we like all we please to no avail, as there is little intellectual continuity from decade to decade on many issues to which the 'social sciences" are relevant) but of the deracination of human sexuality that took place during the late Sixties and Seventies.
In other words, personal and social pathology are created by the desacralization and trivialization of human sexuality, not by its delimitation and channeling within within the confines of the marriage covenant. The standard old self justificational leftwing nostrum that personal self control
creates pychopathology (the underlying assumption being that human beings are rabid sexual animals festering with lust on a continual basis that if frustrated by Judeo/Christian moral boundaries simmers to the boiling point and than explodes in various psychological symptoms (hence, Huge Hefner's theory that war is caused by dried up old men who haven't been laid in a very long time)), is still with us, and wants to Trump the much more rational and historically grounded view that the development of personal self discipline in the areas of human appetites and passions tends, as one might expect if one is serous in its persuit and holds such values as important, toward precisely the restraint that is sought, and, as this study points out, tends towards other benefits that must be weighed against the overarching Liberal principle of orgasm at any cost.

The very obvious and historically supported rejoinder to all this is that it is precisely the cutting loose of the sexual boat from the moorings of the sacred as well as from the idea that human sexuality is little more that the romantic or recreational business of two isolated individuals, and has no implications beyond those two (the larger community, its moral fabric, future generations etc.), that produced the inevitable psycho/social pathologies so pervasive in and indicative of the post Sixties world in which we live and its fundamental philosophical substrate, relativism.
