Difference between mani and mazi

Q: I get a pressing feeling when seeing bad videos (sexual). But when i do press and pull penis from bottom to top to make all madhi out which is inside penis, then madhi will be coming out as big drop, then inside the big drop small white particle would be there or if i take that drop between my fingers and then look through it to a light, then i notice slightly thin and white line or two line inside madhi, where madhi is transparent. And that white thing does not come separately but always along with madhi but very less quantity of white thing. I get that white thing along with madhi when i get pressing feeling.

1. Is that white thing mani or madhi?

2. Is the colour of madhi always transparent?

3. Isn't ghusl fard only if a person experiences full sexual discharge?

Note: Pressing feeling means I get aroused and penis erected. I get feeling like pressing and releasing at bottom of penis. Similar to wet dream time when reaching climax and ejaculation happens. But it is not full sexual discharge as while it happens in wet dreams. Pressing and releasing feeling comes continuously during wet dreams, but while i am awake it comes once and after sometime twice or once, But not continuing consecutively but after some time. In wet dream there is no gap between pressing and releasing feeling it goes on continous till all mani is ejaculated.

Getting the reward of an action if one made waseelah through that action

Q: There is hadith in 'Fazail A'mal' about three persons who got trapped in a cave. In order to escape from that they gave wasila to Allah Ta'ala of one of their good deeds each. Then Allah Ta'ala made way for them to escape.

I want to ask: If a person is in some sort of trouble and if he asks Allah Ta'ala in the above mentioned manner, then the good deed which he gave wasila of, will the "ajar" (reward) of that deed get finished or will he get that deed's "ajar" (reward) in the afterlife also?
