How can an ordinary person differentiate between prostatic fluid (madhy) and sweat or other fluids on clothes and body? Is it obligatory to inspect clothes and the penis every time one feels something has been discharged, especially given the frequent and difficult nature of this sensation? What should be done if a drop of water exits after washing the organ? What is the sufficient amount of water for istinja' (ritual cleansing) from urine and madhy? What should one do if they feel wind or madhy being discharged during Tawaf? Is it permissible to perform wudu' for each prayer time in this situation?

"Waswasah" (whisperings/obsessive thoughts) is a chronic illness, and its cure lies in not indulging it or paying it any attention, but rather in completely disregarding it. So, if you doubt the emission of madhy (pre-seminal fluid) or wind, do not pay attention to this doubt unless you achieve absolute certainty. This approach applies to 'Umrah (definition) and other acts of worship. If you perform ablution, proceed with your worship unless the doubt reaches the level of certainty that your ablution has been invalidated. As for istinja (definition)' (washing after defecation/urination), its purpose is to achieve cleanliness, and a strong presumption is sufficient for it. What you mention about water coming out after istinja' is most likely from waswasah.
