Imaamat of a ma'zoor

Q: Since last few months there’s minor fluid leaking from my anus, as soon as I clean myself and make wudhu, it leaks again. I think I qualify to be a Ma’zoor.

1. I have lead some prayers at home being a ma’zoor, are my prayers valid? If not, do I have to repeat them and inform my friends who prayed behind me. I don’t remember some persons who prayed behind me.

2. Can I offer Nafl Fasts in this state?

3. As the wudhu expires at the end of every salah time. Is it ok if I perform wudhu 5 mins before Maghrib as the jama’at time starts right after Adhan. I perform wudhu for Tahajjud Salah (20 mins before Fajr), do I have to perform fresh wudhu after Fajr time begins?
