In Jainism, sexuality is treated with restraint and responsibility.

• Within marriage: Sex is generally allowed and considered a natural part of life for householders, but it is best kept within the bounds of a faithful, respectful marriage. Fidelity and non-harm to one's partner are important.
• Premarital sex: Premarital sexual relations are typically discouraged or discouraged strongly, as they can lead to attachment, karmic consequences, and distractions from spiritual discipline. The aim in Jain practice is to cultivate self-control (brahmacharya) and ahimsa (non-harm) in all aspects of life.
• For renunciants: Brahmacharya (celibacy) is a core vow. Any sexual activity is not permitted.
• Ethical considerations: Jain thought emphasizes consent, mutual respect, privacy, and avoidance of exploitation or harm. Sex is not just a physical act but also a matter of moral discipline and spiritual progress.

There are minor differences in emphasis between Digambara and Śvetāmbara traditions, but both traditions uphold sexual restraint outside a devoted, monogamous marriage and value celibacy for monks and nuns.

If you’d like, I can share some specific teachings or verses from Jain scriptures that discuss chastity, self-control, and the right to lead a virtuous household life.
