Yes, in Digambar Jainism a female layperson can be reborn in a heaven realm if she has earned strong puṇya karma through good conduct, restraint, compassion, charity, and right faith.

But please note:

• Watching 18+ content many times creates harmful karma because it increases attachment, passions, and mental impurity.
• That karma is not “undone” instantly, but it can be reduced and cleansed through:

- sincere repentance - pratikraman - stopping the habit - self-control - avoiding further harm - practicing ahiṃsā, brahmacharya, and aparigraha

Also, in Digambar Jainism, heaven is not moksha. It is only a temporary birth, and after that the soul continues in saṃsāra.

About a female birth:

• Yes, a woman can go to heaven.
• But in Digambar tradition, final liberation in that same female birth is not accepted.

So the short answer is:

• Can the karma be purified? Yes.
• Can a female layperson go to heaven? Yes.
• Is heaven final liberation? No.
