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

[KoShiatar]

I started to think the Fool can shift genders, or that perhaps his body is simply made differently from that of other human beings, and gender matters little to him. Remember when Fitz notices that he is, after all, different like he claims, and that he has a few strange physical characteristics such as the way his hands are attached to his wrists. Also his sexual tastes (or lack thereof) are indication of this.
