Jainism does not have a specific ban on BDSM as a labelled practice. What matters in Jain ethics are core principles like ahimsa (non-harm), satya (truth), brahmacharya (celibacy or controlled sexuality), and aparigraha (non-attachment/ascetic restraint).

• For monks and nuns (digambara/shwetambara alike): celibacy is a fundamental vow, so sexual activity is not allowed.
• For lay Jain households: sexual conduct should be within the bounds of mutual consent, fidelity, and non-harm. Any sexual practice that harms a partner, involves coercion, deceit, or exploitation, or distracts from spiritual progress would be contrary to Jain ideals.
• Overall guidance: Jainism encourages self-control, respect for others, and reducing desires that lead to harm or bondage of the mind. If a practice is harming someone or oneself or undermines ethical conduct, it would be discouraged.

In short, Jainism is not about banning BDSM by label but about preventing harm, promoting consent and respect, and fostering self-discipline and spiritual progress.
