In Jain Dharma, uncontrolled sensual thoughts and desire mainly bind _Mohaniya karma_ — especially _charitra-mohaniya_ (deluding karma that disturbs right conduct). Because of lust, attachment, and craving, one also attracts other pāpa karmas through mind, speech, and body.

In simple words:

If a person keeps indulging in sensual thoughts, then the bondage becomes stronger in these ways:

• Mohaniya karma — delusion, attachment, passion, and lack of control
• Punya or pāpa result depends on intent and restraint, but sensual attachment usually causes pāpa bondage
• It also supports the bondage of other karmas because the soul becomes more restless and less disciplined

For married people:

In Jainism, marriage is not a license for uncontrolled desire. A married person is expected to live with:

• fidelity
• restraint
• contentment
• respect
• limit in sensual enjoyment

If a married person uses marriage only for sense pleasure and attachment, then karmic bondage still happens. If husband and wife live with dharma, self-control, and reduced passion, the bondage is much less.

Important Jain principle:

• Monks and nuns keep complete celibacy
• Householders follow limited restraint
• For householders, the goal is not indulgence, but control of desire

So, the real issue is not only whether a person is married or unmarried — it is whether the mind is under control or under lust.

If you want, I can also explain this in terms of specific karma categories in Jain karma theory, in simple language.
