In Jainism, controlling the senses and practicing brahmacharya (celibacy or sexual restraint) are important moral disciplines. The general teaching is that pornographic content harms this discipline by arousing passion, objectifying others, and fostering attachment, which can generate negative karma.

• For monks and nuns: strict vows of celibacy and sense-control are mandatory.
• For lay Jains: sexual behavior should be restrained and respectful, ideally within ethical boundaries, and one should avoid sensual media that inflames desire or harms others.

So, while not every Jain might speak about it in the same words, the mainstream Jain view is to avoid porn because it undermines self-control, ahimsa (non-violence), and spiritual progress. If you’d like, I can explain how Digambar and Śvetāmbar traditions treat brahmacharya differently.
