In Jainism, sex outside proper ethical bounds is classified as sexual misconduct (kāma-paāp). Engaging in such acts, including with a prostitute, inflows karmas driven by attachment, desire and deceit. These karmas bind you further to the cycle of birth and death and darken spiritual knowledge and perception (jnāna-varoṇa and darśana-varoṇa), making spiritual progress harder.

Key points:

• Sexual misconduct is listed as one of the main non-virtuous activities that create paāp karmas.
• These karmas increase passion (kṛṣā/kaama) and lessen self-control, leading to more suffering in future lives.
• The exact emphasis or ritual detail can differ between Digambara and Śvetāmbar traditions, but both treat sexual misconduct as serious spiritual fault.
• For monks and nuns, sexual activity is strictly prohibited; for lay Jains, it is expected to be governed by restraint and fidelity within appropriate ethical norms.

If you’d like, I can explain how this topic is described in specific Jain scriptures or stotras in a way that shows the exact Sanskrit terms and their Jain interpretations.
