In simple words:

A “blowjob” is a kind of sexual act (oral sex) where one person uses their mouth on another person’s sexual organ. Yes, it is a form of sex.

From a Jain Dharma point of view:

• For householders (shravaks/shravikas):

- Sex is allowed only with one’s married partner, and even then, with restraint and modesty. - Any form of excessive, lustful, or unnatural sexual activity (including oral sex, porn, etc.) increases kasāyas (passions like lust, attachment) and leads to pāpa (bad karma). - It goes against the vow of Brahmacharya Anuvrat (limited celibacy / controlled sexuality).

• For sadhus and sadhvis:

- All sexual activities (even thoughts) are totally forbidden. They follow complete brahmacharya.

Jain viewpoint focuses on:

• Controlling indriya-sukha (sense pleasures)
• Reducing āsakti (attachment)
• Keeping the mind shuddha (pure) and peaceful

So, in Jainism, any sexual act done just for pleasure, excitement, or lust is discouraged and seen as harmful for spiritual progress.
