Factors that break ghusal

Q: I woke up in the morning and found my self a little wet i.e some ejaculation and I didn't have any dream of having sex or being seduced. So do I have to bath before praying?

Q: I am a 22 years old male. I am getting white fluid discharge frequently from my penis without any sexual arousal and without any erection. But when I am sexually aroused I get sticky colorless fluid discharge. For the past five months, I do ghusal almost every morning because of this white fluid discharge thinking that it may be mani (semen) to be on safer side. It becomes difficult for me to pray Fajr on time. I am very much depressed. Doctor found no problem with me. It is not thick as mani. I don't know whether sperm is present in this white fluid discharge. When I am awake I wash private parts and do wudu. But my question arises only after sleeping everytime. My question is:

1) Do I have to do ghusl every time when I get this white fluid discharge when sleeping? (90% of the days I don't remember having erotic dreams) 2) Is this mazi or mani? (semen)?

Note: This white fluid comes even when I am not sexually aroused. It comes not more than 2 or 3 drops every time.

Q:

1. If a man has a wet dream and finds wetness on his garment but the wetness is less than a diameter of 2.75cm, is ghusl still necessary?

2. If a man finds mazi of a diameter less than 2.75cm but he does not remember having a wet dream, is ghusl still necessary?

Q: I was getting help from the teacher for a questions and I was sitting and some bad sexual thoughts came to my mind and I randomly was shaking my leg to and the thought gave me a weird feeling in my private area but soon left also I was shaking my leg but not for the purpose to get rid of that feeling as soon as I realized I even was shaking my leg I stopped but since I was concentrating on my work the thought left my mind and later when I got up I felt a slight bit of wetness and when I came home there was a bit of discharge. Am I napaak?

Q: If I sleep only 2 or 3 minutes and I have a wet dream in this short nap but I am sure and totally aware that I had no orgasm and also don't feel any sensation at private area but released mazi not mani, so ghusl is fardh?

Q: If l remember a wet dream and find wetness but wetness is not mani or mazi but this wetness is vaginal discharge and sweat, so ghusal is compulsory?

Q: Sometimes when I'm doing a workout at home, without fantasizing or touching my private parts there is a discharge of semen with excitement. This has happened a few times now. Is this Haraam?

Q: My question is if my husband goes out of state or girlfriend boyfriend are having a conversation on the phone, while talking on the phone they started to have romantic conversation or started kissing while on the call and you start getting discharge while all this is happening. Is that discharge napaak or paak?

Q: After spending time with my husband and a fard ghusal is necessary I will urinate and then take a bath. Usually always semen will come out while I am bathing too. Nowadays to waswasa I have bad thoughts while bathing and than of course I try to push it away and then I see seman coming out. I know the semen is because I have spent time with my husband and not because of the thoughts so sometimes I'll just finish the ghusal but will feel guilty the whole day until I make a new ghusal. What should I do?
