Is thinking about sex a sin for a divorced woman? Is masturbation forbidden in her case? And is the emission of fluid without it considered impure and does it necessitate ghusl?

There is no benefit in thinking about matters of intercourse. The questioner should direct her thoughts to what benefits her in her religion and her worldly life. We advise her to fast, as it weakens desire. As for masturbation, it is forbidden except out of necessity, such as fear of committing fornication, and necessity is determined by its extent. As for the discharged fluid, if it is semen, then ghusl (ritual bath) is required, and the preponderant opinion is that it is pure. If it is madhiy (pre-seminal fluid), then ablution is required, and the private parts should be washed from it, as it is impure.
