Emission of maniy without desire does not invalidate the fast
Question

Maniy comes out of me every day during the month of Ramadan, which prevents me from fasting. Please note that this does not happen on ordinary days. Is this because of weakness of faith? Please note that I do not have any sickness. What should I do, especially since the blessed days of Ramadan go by without me fasting? Please note: I went for ‘Umrah a month ago and the same thing happened. I hope you can advise me.
Praise be to Allah.It is not clear to us what you mean by saying “Maniy comes out of me every day during the month of Ramadan.” 
1.If what is meant is that you have a wet dream and maniy is emitted as a result, that does not affect the fast, because it is not under a person's control.
2.If what is meant is that maniy comes out whilst you are awake without you doing anything, rather it comes out by itself and you are certain that it is maniy, then in most cases this results from sickness. The majority of scholars – Hanafis, Maalikis and Hanbalis – are of the view that this does not necessitate ghusl, and this is the correct view. See the answer to question number 84409. The fast is not invalidated by the emission of this maniy, because it is involuntary and is beyond a person's control.
Ibn Qudaamah (may Allah have mercy on him) said: If he masturbates with his hand, then he has done a haraam action, but he is fast is not invalidated by it unless he ejaculates. If he does ejaculate, then his fast is invalidated. But if he ejaculates without desire, such as a person from whom maniy or madhiy comes out because of sickness, there is no blame on him because it came out without desire, and is similar to urinary incontinence; and because it came out without him choosing that or causing it, so it is like a wet dream. End quote from al-Mughni (3/21).
To sum up: if maniy comes out without any action on the part of the fasting person, whether by using his hand or by intimacy or repeated looking, then his fast is not invalidated. Usually when maniy comes out in this manner, it is due to sickness or disease.
3.With regard to the one who masturbates or causes maniy to be emitted by his hand, or by repeatedly looking at that which provoked his desire, this does invalidate his fast, as well as being a major sin, because he has committed two haraam actions, the first of which is masturbation and the second is deliberately breaking the fast during the day in Ramadan. This is a grave major sin concerning which there is a warning as was narrated by Ibn Khuzaymah (1986) and Ibn Hibbaan (7491) from Abu Umaamah al-Baahili (may Allah be pleased with him) who said: I heard the Messenger of Allah (blessings and peace of Allah be upon him) say: “Whilst I was sleeping, two men came to me and took hold of my upper arm, and brought me to a rugged mountain. They said: ‘Climb up.’ I said: ‘I cannot do it.’ They said: ‘We will make it easy for you.’ So I climbed up until I was at the top of the mountain. There I heard loud voices. I said: ‘What are these voices?’ They said: ‘This is the screaming of the people of Hell.’ Then I was taken and I saw people suspended by their ankles, with the corners of their mouths torn and pouring with blood. I said: ‘Who are these?’ They said: ‘These are the people who broke their fast before it was time to do so.’” Classed as saheeh by al-Albaani in Saheeh Mawaarid al-Zam’aan, no. 1509.
4.You may be confused about the matter so that you do not distinguish between maniy and madhiy/wadiy; both of the latter do not invalidate the fast.
This is how to distinguish between these things:  
Madhiy is a thin, clear liquid which comes out during foreplay or when thinking of intercourse or desiring it or looking; a person may be unaware of it. 
Wadiy is a thick white liquid which comes out in white drops, usually after urinating. Both of them are najis (impure) and invalidate wudoo', but the najaasah (impurity) of madhiy is less serious and it is sufficient to sprinkle water on it, which means making water reach the entire area that it got onto, without squeezing or rubbing. 
Ghusl is not required in these two cases and the fast is not invalidated by them. 
As for maniy, it is a white liquid that is emitted with forceful gushing, followed by lassitude. When it is wet it smells like dough or the spadix of a palm tree, and when it is dry it smells like egg whites. It is taahir (pure) but it necessitates ghusl, except if it is emitted whilst awake without desire, as stated above, in which case it does not require ghusl. 
With regard to that happening to you when you were travelling for ‘umrah, if that occurred during a wet dream whilst you were sleeping, then you have to do ghusl and it is not permissible for one who is junub to enter al-Masjid al-Haraam or to circumambulate the Ka’bah. If that happened during the day without desire, then you only have to do wudoo’. 
We hope we have answered your question. If there is still anything that you don't understand, then ask again and we will be happy to help you. 
And Allah knows best.
