From Femboy to Real Girl: Naruto

What kind of book is this? From what I remember, there's a story about marrying a hundred women, which is understandable, but what about bisexuality? Bisexuality? Bisexuality? Can someone tell me if this is going to be a story where the protagonist collects a bunch of girls and then a bunch of cute boys?

I remember there was a book where the protagonist transformed into Tsunade's sister, was it by the same author?
