Factors that break wudhu

Q: Does wudhu break if a small amount of blood comes out from the nose while blowing it, along with mucus?

Q: After passing urine and making wudhu during prayers, if I get cough or sneezing it feels as if some few drops of urine has been passed. Should a fresh wudhu be made if this symptoms continue frequently and regularly?

Q: I have got a fat pimple or wound, which is still open. Its on my hand. It does not bleed when it is dry but when water passes on it, it gets wet, and water sits on it. When I put a tissue on it, the tissue gets stained with a dot of red or yellow colour, a little bigger than a dot. So my question is that since its on my hand, how do I do my wudhu? And the water that touches the wound is paak or napaak? 

Q:

1. If blood is mixed whith phlegm from my nose or mouth is my wudhu broken?

2. Is it paak or not?

Q: Does eating camel meat break wudhu?

Q: Do I have to repeat my Salaah if I find out scotchtape on my feet after immediately performing esha Salaah.

Q:

1. Does the wudhu of a female break if she does not cover her hair and any gair mahram sees her in that state?

2. Is bleeding and vomitting related to breaking of wudhu and fast?

3. What are the things which breaks ones wudhu?

Q: I experience wet drops once I get to my partner without having any physical relation. Can I go for salaah or other things without "ghusal"?

Q: I have a question that if one has an anal fistula (medical condition in which there is a connection between the lower part of the intestine and the skin) and there is a discharge from it which may be mucus, serous, pus or stool at times. It may be small in quantity and one may not even notice it.

1. Would the discharge break the wudhu and nullify the prayer

2. Sometimes I may not even know about the discharge, does one have to check before and after praying each time?

3. Sometime I need to do imamat, in that situation after salat should I ask the congregation to wait and check the discharge? It seems to prevent me from offering salat in congregation and constant fear of losing wudhu.

Q: Everyday I keep doubting whether my wudu was done correctly or should I repeat my wudu. I suffer from ocd.
