Among the world's religions, views on masturbation vary widely. Some religions view it as a spiritually detrimental practice, some see it as not spiritually detrimental and others take a situational view. Among these latter religions, some view masturbation as allowable if used as a means towards sexual self-control, or as part of healthy self-exploration, but disallow it if it is done with motives they consider to be wrong, or as an addiction. For example, Christian denominations have different views on masturbation. Today, Roman Catholic (including Eastern Catholic), Eastern Orthodox, Oriental Orthodox and some Protestant Christians consider masturbation to be a sin. Many Protestant churches in Northern and Western Europe and some Protestant churches in Northern America and in Australia/New Zealand see masturbation as not a sin.

According to Björn Krondorfer, "Auto-erotic sex became conceivable as a distinct entity among sexual sins only when the autonomous self emerged." He goes on to cite Laqueur, "Only after the Freudian revolution...did a cultural shift occur. Masturbation was now valued as an adult, non-pathological, pleasurable activity. 'Beginning in the 1950s, picking up energy with the feminism of the 1960s and early 1970s, with the subsequent sex wars, and with the worldwide gay movement of the last quarter of the century, it would become an arena of sexual politics and for art across a wide spectrum of society...Due to this cultural change across the spectrum, even theological reassessments of masturbation as a positive sexual practice were possible – though, admittedly, rare."

A 2016 Psychology Today article stated that the more religious people are, the more likely they are to restrict their sexual fantasies, have fewer sex partners, use less pornography and express stronger disapproval of the use of sex toys.
