I'm not sure of specific 'nanny boy novels' off the top of my head. But you could try looking into books that deal with characters who break gender norms. For example, 'The Perks of Being a Wallflower' has characters that are complex and might have some elements that could be related.
Honestly, it's a rather specific type of novel and not a common genre label. But some books that explore non - traditional male characters could potentially be what you're looking for. 'A Single Man' by Christopher Isherwood features a male protagonist who has a very refined and somewhat un - macho way of living. His attention to detail and self - awareness might be similar to what could be expected from a 'nanny boy' in the sense that he doesn't conform to the typical male stereotype. You could also search for books in the LGBTQ+ literature section as they often have characters that break gender norms and might have the kind of character you're thinking of in a 'nanny boy novel'.
