In Jain Dharma, the vow related to sexual conduct is brahmacharya or svadār-santosh in the lay context, meaning restraint and avoiding sexual misconduct.

Traditional Jain texts do not specifically discuss homosexual acts as a separate category. They judge conduct by the principles of:

• restraint
• non-indulgence
• fidelity
• avoidance of lustful behavior
• avoidance of harm and loss of self-control

So, from a Jain lay-vow perspective, the main issue is whether the conduct breaks sexual restraint. Any sexual act that is considered unrestrained, lust-driven, or outside the limits of one’s vows would be seen as contrary to the vow.

For a layperson, Jainism generally emphasizes:

• proper conduct
• self-discipline
• limited sensuality
• purity of mind, speech, and body

So the answer is: Jainism does not single out homosexuality by identity, but sexual conduct is evaluated by the vow of restraint; if it violates that restraint, it is against the lay vow.
