Religion's historical mistrust of sexuality shapes people's behavior by inhibiting liberal sexuality. Still, it is unclear whether this inhibitive role also includes common, normative sexual behavior, particularly in secularized contexts. Moreover, the possible mediating effects emotions, affects, and thoughts have on the association between religiosity and restricted sexuality have never been integrated into a single model. Finally, cross-religious differences in common sexual behavior have still yet to be documented. We addressed these three issues in two studies, with samples of Catholic and Muslim tradition (total N = 446). Consistently across samples, religiosity predicted, either directly or indirectly, less frequent common heterosexual behaviors and masturbation, partly through sexual guilt and inhibition, and/or decreased sexual fantasy and the search for sexual pleasure. However, married Muslims’ religiosity, unlike Catholics’, did not directly undermine fertility-oriented sexuality and the search for pleasure. Religion's role in restricting sexuality seems to be rooted in deep psychological rationale.

In contrast with traditional considerations, sexuality is often perceived today as being rather compatible with religion/spirituality and morality. However, there may be some inherent opposition between (a) sexuality (thoughts, affects, and pleasure) and (b) religion/spirituality (attitudes, motives) and (interpersonal) morality (dispositions, behavior). The two imply, respectively, self-enhancement versus self-transcendence, disinhibition versus selfcontrol, and disgust indifference versus sensitivity. We hypothesized that sexual experience attenuates spiritual and moral concerns and behaviors. In three online experiments, young adults were asked to recall a personal sexual experience. Compared to a control condition, sexual induction diminished spiritual behavioral intentions (Experiments 1 and 2), in particular among those with high individual disinhibition (Experiment 1), as well as behaviors of prosociality and integrity/honesty (Experiment 3). The effects were independent of individual religiousness/spirituality. These findings suggest that combining sexual pleasure with self-transcendence and moral perfection, even if a legitimate ideal, is not an easy enterprise.
