From a Jain perspective, yes, you should stop.

Selling nudes online for money is generally seen as not aligned with Jain values, because it can involve:

• Brahmacharya — preserving chastity, restraint, and purity
• Aparigraha — reducing attachment to money, validation, and desire
• Ahimsa — avoiding actions that increase passion, lust, and harm to yourself and others
• Self-discipline — living with dignity and inner restraint

Jain Dharma teaches that actions which increase kashāyas like rāga (attachment) and kāma (desire) make spiritual progress harder. So if you truly want to live as a Jain, this path is not compatible with that goal.

If possible, stop gradually and choose work that supports your life without violating Jain principles. Also, do not hate yourself for past actions—Jainism emphasizes repentance, correction, and purification.

A simple Jain way forward is:

• stop the activity
• avoid repeating it
• do pratikraman sincerely
• strengthen restraint, purity, and self-respect

If you live by Jain ideals, your body, mind, and actions should reflect discipline, non-attachment, and dignity.
