No. In Jainism, blessings from teachers or Tirthankaras are sought through ethical conduct, prayer, meditation, repentance, and following the teachings, not through any sexual or inappropriate ritual.

Jain practice emphasizes reverence, humility, and adherence to vows (like ahimsa, satya, aparigraha), and respect for gurus or teachers is shown in modest, respectful ways (such as folded-hands namaskar or bowing in humility and listening to their guidance), but not through sexual acts or intimate contact.

If you’d like, I can share more about how reverence for teachers and the Tirthankaras is expressed in Digambar and Shwetambar traditions.
