In Jainism, the main concern is conduct, not labeling a person by orientation.

• Ahimsa: no harm, exploitation, coercion, or deceit
• Brahmacharya / restraint: self-control over sexual desire
• For monks and nuns: complete celibacy is required
• For householders: sexual conduct should be disciplined, respectful, and non-harmful

Jain scriptures and tradition do not usually discuss homosexuality in modern terms. So Jainism does not frame same-sex attraction as a sin by itself. The ethical question in Jainism is whether the relationship is consensual, truthful, restrained, and non-injurious.

So, in simple terms: being homosexual is not inherently against Jain principles, but Jain ethics still expect self-restraint, purity of conduct, and non-violence in any relationship.

If you want, I can also explain this from the householder view and the monastic view separately.
