From a Jain perspective, the key is self-control and non-violence (ahimsa) in all senses.

• For monks and nuns: complete celibacy is mandatory.
• For householders: the ideal is Brahmacharya (continence of mind and body). Sex is ideally kept within a committed, respectful marriage and should not involve harm, coercion, exploitation, or excessive passion. The aim is to cultivate inner detachment and spiritual progress, not merely physical pleasure.
• Masturbation: generally discouraged in Jain teachings because it stems from uncontrolled sensual desires and can disturb one’s focus on non-attachment and purification. It tends to arouse cravings that hinder spiritual progression.

In both Digambara and Śvetāmbara traditions, the emphasis is on restraint, ethical conduct, and mindfulness of how actions affect others and one’s own spiritual path. If you’re seeking a precise doctrinal nuance, a trusted Jain scripture or teacher in your tradition can give the exact stance for your community.

If you’d like, I can point you to Jain texts or commentaries specific to your tradition (Śvetāmbara or Digambara) for a more exact arth.
