Respecting one's father

Q: I belong to a very poor family, because my father sold all of his land, house, goods, etc. because he is addicted of all kinds of intoxications including women. Now he is stealing from people.

A few years back, my mama started working as a maid servant to bring us up. Now I am grown up and I cannot bear these things any more. I beat up my father when he steals something but he never stops.

I kicked him out from my house because I cannot explain what it is to live with my father. Will Allah forgive me? I do not want to do this but I am tired and can't bear this anymore.

Will one be a ma'zoor by emitting few drops when aroused?

Q: I have been experiencing a few problems lately. Often when I experience an erection, a few drops of what I believe to be semen. I have never had a wet dream so I don't really know what it should look like. This does not happen everytime but it does occur.

a) Am I considered to be mazoor?

b) If not do I have to have a bath every time that happens?

c) If i am mazoor do i have to have a every time?
