Washing Bedclothes after Sex, Obligatory?
As regards your question, Sheikh Muhammad Salih Al-Munajjid, a prominent Saudi scholar, stated,
“If the fluid is that drops on the bedclothes is maniy (semen) and is not mixed with any other secretions, then you do not have to wash the bedclothes because maniy is tahir (pure), according to the correct scholarly opinion.
But if what gets onto the bedclothes is madhiy (prostatic fluid) or some other secretion that comes from the private parts of the man or the woman, then you have to wash only the spot where this fluid lies, because these secretions are regarded as najis (impure).”
As for your madhy, it is a sticky white fluid that is emitted when a person is thinking of or desiring intercourse. Its emission is not accompanied by feelings of pleasure, it does not gush out in spurts, and it is not followed by exhaustion. This may happen to men and women alike, although it is more common among women.
May Allah guide us to what pleases Him!
