Please note that if the discharge of maniy is accompanied by feelings of desire, ghusl is required according to scholarly consensus. See al-Majmoo’, 2/111; al-Mughni, 1/266 

With regard to maniy being discharged with no feelings of desire, the scholars differed concerning that. The most correct view is that if it is emitted with no feelings of desire, ghusl is not required but you have to do wudoo’. The evidence for that is the words of the Prophet (peace and blessings of Allaah be upon him) to ‘Ali ibn Abi Taalib (may Allaah be pleased with him): “If water gushes forth then ghusl is required.” Narrated by Abu Dawood, 206; classed as saheeh by al-Albaani in al-Irwa’, 125. See also al-Sharh al-Mumti’, 1/278. “Gushes forth” means that it comes out forcefully, with feelings of desire. 

One has to distinguish between the kinds of discharge that come out; not every discharge that comes out of the private part is maniy for which ghusl is required. There is wadiy (a kind of fluid emitted after urination), maniy (fluid emitted at the point of climax) and various discharges experienced by women. 

You have to know the difference between these and be able to distinguish between them. Madhiy and wadiy do not necessitate ghusl, rather what is required is to wash the private parts with water and do wudoo’. 

It is proven in al-Saheeh that ‘Ali (may Allaah be pleased with him) said: “I was a man who used to emit a great deal of madhiy, so I told al-Miqdaad ibn al-Aswad to ask the Prophet (peace and blessings of Allaah be upon him) about that. He asked him and he said: ‘Wudoo’ is required for that.’” Narrated by al-Bukhaari, 132; Muslim, 303. 

These discharges are not naajis (impure), but they break wudoo’. See question no. 7776.  

If the emission of maniy is accompanied by feelings of desire, then ghusl is required. If it is not accompanied by feelings of desire then ghusl is not required. Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) said:  

The difference between maniy and madhiy is that maniy is thick and has a smell, and it comes out in gushes when desire intensifies. Madhiy is a thin liquid that has no smell, and it does not gush out or come out when desire intensifies, rather it comes when desire has calmed down. 

Wadiy is a liquid that comes out after urinating, a few white drops that appear at the end of urination.

 This is a description of these three things. 

With regard to the rulings on them, wadiy is subject to the same rulings as urine, in all aspects. 

Madhiy is somewhat different to urine with regard to purification, because it is less naajis, so it is sufficient to sprinkle water on it. So one should put water on the area (of the clothes) affected, without squeezing it or rubbing it. Similarly a man should wash his entire penis and testicles even if no madhiy got on them. 

Maniy is taahir (pure) and there is no need to wash what it gets onto, unless that is to remove any marks or traces, but it necessitates ghusl. Madhiy, wadiy and urine, on the other hand, necessitate wudoo’.
