Factors that break wudhu

Q: I would like to know if someone sleeps for few minutes whilst sitting on a chair or car seat or aero plane seat, will his wudhu break?

Q: Does ablution break when you have confusion that ablution broke or not?

Q: Should a woman perform wuzu again and again for every namaaz after breastfeeding a baby?

Q: Fajr time I came out of washrum offered namaz then when I opened the book to recite surah yasin I felt some warm drops in my private parts. I thought that it was a waswasa and continued but after reciting I checked. There was very little moisture on my thighs and there were drops in my private parts which can be the result of water I used during istinja. I don't understand whether I was in wudhu or not?

Q: I was performing Maghrib Salaah when suddenly my nose began to flow with blood. I continued with my Salaah till the end. I am not sure whether my Salaah is valid or not?

Q: What must a woman do if she has a problem of clear discharge all the time. Even after making wudhu and during salaah and while reading quraan? Please advise regarding wudhu.

Q: Does having any sexual thought or arousal after ablution invalidate wudu?

Q: 

1. Can I read namaaz with the same wudu which I made before ghusl?
2. I have wudu and I changed clothes infront of my wife, do I still have wudu?

Q: If a girl thinks of the opposite gender, some normal day to day things, nothing romance and she is not sure that something has came out of her private parts. She suffers a lot of vaginal discharge everyday. So she performs her namaaz but afterwards she sees a white mark on her pants. Must she repeat her namaaz?

Q: I find wetness in my private parts all day long (75 percent of time in 24 hours). It's watery. When it dries I can't see anything. After istinja if I wipe it, I still find some drops there. Today when I got up for fajr, I found watery substance with no colour in it. There was no stickyness. I was not even feeling like urinating and if sometime Ii feel like urinating during day or night it does not mean that I will just do it. I am highly confused for my taharat (purity). What should I do for offering namaaz? Are my clothes and myself impure? I can't wear panty and liners all day long, it creates itchiness.
