My prostatic fluid flowed excessively. I used to take a bath until my back cracked (because of frequent washing). I mentioned it to the prophet (May peace be upon him), or the fact was mentioned to him (by someone else). The Messenger of Allah (May peace be upon him) said; Do not do so. When you find prostatic fluid, wash your penis and perform ablution as you do for your prayer, but when you have seminal emission, you should take a bath.  

كُنْتُ رَجُلاً مَذَّاءً فَجَعَلْتُ أَغْتَسِلُ حَتَّى تَشَقَّقَ ظَهْرِي فَذَكَرْتُ ذَلِكَ لِلنَّبِيِّ ﷺ أَوْ ذُكِرَ لَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ لاَ تَفْعَلْ إِذَا رَأَيْتَ الْمَذْىَ فَاغْسِلْ ذَكَرَكَ وَتَوَضَّأْ وُضُوءَكَ لِلصَّلاَةِ فَإِذَا فَضَخْتَ الْمَاءَ فَاغْتَسِلْ  

I was a man who emitted a great deal of madhi and I started to do ghusl in the winter, until the skin of my back became cracked. I mentioned that to the Prophet ﷺ, or it was mentioned to him, and he said: “Do not do that. If you see madhi, then wash your private part and do wudoo’ as for prayer, but if water gushes out, then do ghusl.ʿ (Using translation from Aḥmad 868)  

كُنْتُ رَجُلًا مَذَّاءً فَجَعَلْتُ أَغْتَسِلُ فِي الشِّتَاءِ حَتَّى تَشَقَّقَ ظَهْرِي فَذَكَرْتُ ذَلِكَ لِلنَّبِيِّ ﷺ أَوْ ذُكِرَ لَهُ فَقَالَ «لَا تَفْعَلْ إِذَا رَأَيْتَ الْمَذْيَ فَاغْسِلْ ذَكَرَكَ وَتَوَضَّأْ وُضُوءَكَ لِلصَّلَاةِ وَإِذَا نَضَحْتَ الْمَاءَ فَاغْتَسِلْ»
