What is the ruling on semen exiting with urine after arousal and watching pornography, knowing that no clear semen exited at the time of arousal or thereafter, but rather a turbidity in the urine resembling spermatozoa occurred, and this situation recurs without arousal?

If semen is discharged due to habitual arousal, such as looking or thinking, then ghusl (ritual bath) becomes obligatory, whether it is discharged with urine, before it, or after it. The discharge of semen after the cessation of pleasure does not preclude the obligation of ghusl. However, the discharge of semen without arousal does not necessitate ghusl according to the majority of scholars, and this is the most preponderant opinion. It is imperative to beware of watching pornographic films and to repent to Allah from them.
