I used to get emotional urethral discharges frequently and felt shy to ask Messenger of Allah ﷺ about it. So I requested Al-Miqdad bin Al-Aswad to ask (the Prophet ﷺ ) about it. Al-Miqdad asked him and he replied, "One has to perform ablution (after it)."
عَلِيٌّ كُنْتُ رَجُلاً مَذَّاءً فَاسْتَحْيَيْتُ أَنْ أَسْأَلَ رَسُولَ اللَّهِ ﷺ فَأَمَرْتُ الْمِقْدَادَ بْنَ الأَسْوَدِ فَسَأَلَهُ فَقَالَ «فِيهِ الْوُضُوءُ۔»
