In Jainism, the guiding principle for sexual conduct is brahmacharya (control over sensual desires) and non-harm (ahimsa). For householders, sex is generally permitted only within a faithful marriage and should be moderate and non-exploitative. Ascetics (monks/nuns) take vows of complete celibacy.

There isn't a specific, canonical prohibition or allowance written about the exact act of anal sex in Jain scriptures. The emphasis is on self-control, reducing attachment to sexual pleasures, and avoiding acts that inflame passions or cause harm. Most traditional guidance would frame sexual activity as something to be carefully restrained and confined to lawful, non-harmful marriage for laypeople, with total celibacy for ascetics. Digambar and Śvetāmbara communities share this basic ethic, though exact practical interpretations can vary by tradition and teacher.
