In Jainism, sex is regarded as one of the five main senses and is closely associated with attachment (raag) and passions (kashayas), which are seen as obstacles on the path to liberation (moksha). Jain teachings emphasize self-control (brahmacharya) and detachment from sensual pleasures.

For householders (śrāvakas), moderate and faithful sexual relations within marriage are permitted, but indulgence or promiscuity is discouraged because it increases attachment and karmic bondage. One of the Twelve Vows (vratas) for laypersons is to observe celibacy outside of marriage.

For monks and nuns (śramanas), complete celibacy (absolute brahmacharya) is strictly observed. Sexual activity, even in thought, is considered a serious violation and leads to the accumulation of karma, which hinders spiritual progress.

Overall, Jainism teaches that minimizing sexual activity and eventually renouncing it entirely is essential for spiritual advancement, as it helps reduce passions and attachments, leading the soul closer to liberation.
