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?

Breaking an oath

Q: In my past I have made vows to Allah saying that I would not do a "sin". For example if I stole something and felt really bad I would repent and say I promise I won’t ever steal again to Allah. The reason I emphasized "sin" is because some of the promises were just misconceptions meaning the "sin" is not really a sin I just promised not to do something thinking it was sinful but in truth it was not a sin. For example if I felt bad that I would delay my prayers I would promise to Allah that I would not delay the prayer ever again. Delaying prayers is not a sin but I made the promise thinking it was a sin. these misconception promises are really hard to keep and I am having a hard time living with them. So, I need to make these promises I made to Allah void or make the promises not count anymore. Is that even possible? How can I do it?

Female working in an old age home

Q: I am a student who works at a taxi call center and I sometimes have to book taxis for people who come and go from bars and night clubs. I have been questioning a lot if my job is haram but I am not sure if I am directly involved in their sins. Because of the uncertanity I decided to apply for a second job in the hopes of quiting this one. I applied for a job at a group home to help seniors and people with disabilities, but I have not taken the job yet as there are different views about a female person working in such settings. I applied for this job because I thought it would be rewarding to take care of someone in need. Is it okay to work there if I take care of women only or if I just help them around the house without having to see their awrah? I am really struggling to find a halal job.
