Religious views on the popularity of sex dolls vary widely, shaped by differing beliefs about sexuality, morality, and the sanctity of relationships. In many Abrahamic faiths—such as Christianity, Islam, and Judaism—sex is typically regarded as a sacred act that occurs within the bounds of marriage. These traditions often discourage any form of sexual expression outside of this framework, particularly when it comes to artificial or non-human partners.

For example, in Christianity, sex dolls may be seen as a violation of the natural order of human intimacy, which should involve mutual emotional and physical connection between a husband and wife. Similarly, in Islam, where sexual relations are considered a private and sacred bond between married partners, the use of sex dolls would likely be viewed as immoral or inappropriate.

However, some more liberal interpretations of religion may allow for personal autonomy in sexual expression, offering less rigid guidelines. In certain Buddhist traditions, for instance, the focus is more on reducing attachment and desire, which might lead to more nuanced discussions about the use of sex dolls as a form of self-expression rather than indulgence.

Overall, while most traditional religious doctrines would likely oppose the use of sex dolls, the rise of these products is sparking new conversations within religious communities about the evolving nature of human desire and sexuality.
