Is the worship of a married woman who watched pornography to learn how to have intercourse accepted, and is God displeased with her, and how can she seek forgiveness while repeatedly committing the sin?

Disobeying Allah leads to evil and tribulation. It is not permissible to watch pornographic films. The questioner must abandon this sin and repent with sincere repentance, which includes forsaking the sin and resolving not to return to it. Acts of obedience and good deeds performed by a disobedient believer are not lost, and they will be rewarded for them. However, their acceptance will be incomplete compared to those who are steadfast in Allah's law. Seeking forgiveness after committing a sin is obligatory. Abandoning seeking forgiveness due to repeated sinning is a whisper from Satan, because Allah is Forgiving and accepts repentance even if the sin is repeated many times. The problem is not in committing the sin, but in persisting in it. One must follow a bad deed with a good deed to erase it, and the best of good deeds here is to increase seeking forgiveness.
