Drinking the leftover water of wudhu whilst standing

Q: What is the ruling of drinking the leftover water of wudhu (fadl wudhu) whilst standing? 

In Dars Tirmizi (vol. 1, pg. 259) — taken from Duroos Madaniyya of Moulana Husain Ahmad Madani رحمة الله عليه — it is mentioned that Ibn Abidin (al-Shami) did not regard it as mustahabb, and that the ahadith on this issue cannot be used to establish istiḥbab. 

However, in Fatawa Mahmoodiyyah (vol. 8, pg. 123) the words of Ibn Abidin (al-Shami) in Radd al-Muhtar are quoted as proof that drinking fadl wudhu whilst standing or sitting is mustahabb. 

My questions are: 

1. According to the Hanafi madhhab, is drinking fadl wudhu mustahabb or not? 

2. What is the correct position of Ibn Abidin (al-Shami) in this matter? 

3. If it is mustahabb, is it specifically recommended to drink it while standing, or is sitting still better? 

4. How should the apparent contradiction between Duroos Madaniyya/Dars Tirmizi and Fatawa Mahmoodiyyah be reconciled?

Spending lengthy periods of time in the shower

Q: I have a urine leak problem. So after I shower I wipe dry then wash close to the slit so that I can be as pure as possible and then dry that water up. At times the water flows away without leaving a bead of water left over and sometimes it leaves a bead.

Now I fear that if that bead of water moves it will go on a part of impurity on my private part, all the water on my private part in some way or the other is connected to each other due to lines/wrinkles on the skin. 

Does it now make the whole private part impure? What would be an easy way in making istinja or even coming out of the shower? 

Sometimes in attempt to get the water to flow off immediately I spend 45 mins plus in the bathroom.
