From the Jain Dharma point of view, you should avoid a “nuru massage.” It is designed to arouse sensual passion and body-to-body contact, which goes against brahmacharya (chastity/self‑restraint). For householders, Jain ethics allow sexual conduct only within marriage and with moderation; for monks/nuns, complete celibacy is required. Seeking sensual stimulation for pleasure increases passions (kashayas), attachment, and karmic bondage, and can also involve subtle himsa through exploitation or objectification.

Helpful Jain guidance:

• Practice self‑restraint and simplicity (aparigraha) in matters of the body and senses.
• If married: keep fidelity and modesty; avoid activities meant only to excite passions.
• If unmarried: observe celibacy and protect the senses through samayik, pratikraman, and swadhyay.
