Semen in the case of men is a thick, white liquid, and in the case of women it is thin and yellow. Madhiy is a sticky white fluid that is emitted when a person is thinking of or desiring intercourse. Maniy requires performance of ghusl, but madhiy requires performance of wudu. Maniy is pure but madhiy is impure.

Muslim bathroom etiquette includes: not facing the qiblah, not touching the penis with the right hand, not removing impurity with the right hand, answering the call of nature sitting, concealing oneself from the sight of others, reciting dhikr when entering or leaving the toilet, and not urinating into stagnant water.

Istinja’ is not necessary each time a person wants to do Wudu. It is essential after passing urine or stools, when a person must wash his private parts before doing Wudu for prayer.
