What is the ruling on my prayers after masturbating, being ignorant of the discharges, and will masturbation negatively affect my relationship with my husband in the future?

One should not despair of repentance; rather, one must persist in it whenever a sin is committed, coupled with abundant supplication, keeping company with righteous women, and shunning causes of temptation. It must be known that a fiancé is a stranger to his fiancée, so flirtatious talk between them is not permissible. Ghusl (definition) (ritual bath) is only obligatory when the emission of semen is certain. If there is doubt about what was emitted, one has a choice. There is no need to repeat prayers about whose purity one doubted after finishing them. As for the effect of this on the relationship between spouses, specialists can be consulted.
