That would feel weird in Hobbit because it's a story he wrote for his kid. At the same time, I find George RR Martin's critique of that aspect of LOTR valid. He said something along the lines of "It's a neat world, but it doesn't feel real. Can you imagine dwarves having sex?" Meanwhile, due to its grit, the GoT world feels very believable. Humans are messy, primal creatures at the core.
