Wudhu

Making another wudhu without having done any act of ibaadat

Q: In Talim ul Haq Masaail pertaining to wudhu it says in number 13 - It is Mustahab (preferable) to make Wudhu for each Salaat even though one may be in the state of Wudhu. It is Mustahab only if at least two Rak'aats Salaat have been performed with the previous Wudhu. Thus if one did not perform any Salaat, it will not be permissible to perform fresh Wudhu before that Wudhu
has been either broken or at least two Rak'aats Salaat have been performed.

1-Is the above correct?

2-Will a person be sinful for doing fresh wudhu, if the wudhu is not broken or two Rakaats hasn't been performed because it says it will not be permissible to perform fresh Wudhu?

Doubts about urine drops

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?
