How sound is the obligation of ghusl (ritual bathing) upon finding wetness in the underwear? Does semen come out with sexual arousal, and how is it recognized? What is the difference between it and pre-seminal fluid (madhy)? Is ghusl obligatory if there was a forbidden glance without lust? And how does a woman see the semen that necessitates ghusl for her according to the Prophetic hadith?

There are distinct differences between manī (seminal fluid) and madhī (pre-seminal fluid). A woman's manī is a thin, yellowish fluid, and may tend towards whiteness. It has two characteristics: its smell resembles the smell of a man's manī (like the smell of palm spathe or dough, and when dry, like the smell of eggs), and its emission is accompanied by pleasure, followed by relaxation. It necessitates ghusl (ritual bath). As for madhī, it is a thin, sticky, white fluid that is discharged upon arousal without gushing or subsequent relaxation. Its discharge may not even be felt. It is impure and necessitates washing whatever part of the body and clothes it touches. It invalidates wuḍūʾ (ablution) but does not necessitate ghusl. Manī is ritually pure according to the preponderant opinion, and it is recommended to wash it off clothes. Its emission necessitates ghusl. Merely looking at something desirable without any discharge does not necessitate wuḍūʾ or ghusl, but if the gaze was unlawful, repentance is obligatory.
