The Fool (spoilers for all RotE books, including LST)

[julia]

For me, Fool is a man. It feels quite possible that the white prophets are hermaphrodites, but I always think about both Fool and Amber as a him.

And I think Fool is making it very clear that he wants to have a physical relationship with Fitz in their argument in Golden Fool.
(I just translated this from the swedish version, so it's probably not as in the original!)

Fool: You know what I feel for you. You've known it for many years. Let's not, you and me, now when we are alone, pretend otherwise. You know that I love you. I've always done so and I will always do.

Fitz: And you know that I love you too. Like a man loves his best friend. I am not ashamed of that. But to let Jek or Starling believe that we would go past the borders of friendship, that you would like to share my bed...

Fool: I love you. My love has no limits. None at all. Do you understand me?

Fitz: Just to well I'm afraid! I would never... Do you understand? I would never want to sleep with you. Ever.

Fool: And that is also something we've both known in all these years/.../Did you really think I would make you do something you didn't want to? I know very well how disgusting you would find that. And I also know that such attempts would destroy everything we have experienced together.

But then on the other hand, he compares their relationship to the Fitz/Nighteye... I'm not sure he even knows what he wants himself..
