In Jain Dharma the key principle here is brahmacharya (chastity / self‑restraint), not “license for enjoyment.”

For a Jain householder (married person)

1. Sex is allowed only with one’s lawful spouse

This is called swadāra-santosh – contentment with one’s own spouse, no adultery, no other partners, no pornography, etc.

1. Main purpose: family life / progeny, not pleasure

Traditional Jain acharyas clearly teach: - Sex primarily for reproduction / family responsibility is within the dharmic framework for householders. - Using sex only as a means of sensual enjoyment and repeatedly seeking it for pleasure increases passions (kashāyas), attachment, and binds heavy karma. This is spiritually harmful, even if it is with your own wife.

1. Moderation and gradual reduction

Even with one’s own wife: - Excessive or frequent indulgence is condemned. - The ideal path for a shrāvaka–shrāvikā is: - Start with restraint and fidelity - Gradually reduce the frequency and intensity - Move step‑by‑step towards greater celibacy, especially as age and spiritual maturity increase.

1. Violence, force, or cheating are serious sins

- No compulsion, no emotional pressure. - Both should agree; conduct must be gentle and non‑harmful, in line with ahiṁsā.

Digambar / Shvetāmbara view

• Both traditions agree on the essentials:

- Monks/nuns: complete celibacy. - Household life: sex only with spouse, with strong restraint, and ideally more and more directed toward reproduction and less toward pleasure.

• Wording and emphasis in texts may differ, but the core teaching is the same:

Less passion → less karma → more spiritual progress.

Direct answer to your question

• Is it allowed to have sex with your own wife when it’s not for reproduction?

- As a householder, this does happen and is not treated exactly like adultery, but: - It is not the ideal, - It should be limited, restrained, and decreasing over time, - Purely pleasure‑driven, repeated indulgence goes against the spirit of brahmacharya and harms your spiritual path.
