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

[maulkin]

To me, the Fool "feels" like neither a woman nor a man. The Fool feels like a child, all be it a wise child, especially in the later books. The love that the Fool feels for Fitz never gives the impression of sexual desire. It seems more like childish affection or infatuation. All in all, the Fool treats Fitz like a beloved (if somewhat dim) elder sibling. Added to this, Nighteyes refers to the Fool as "The Scentless One". This is presumably due to the Fool's alien nature but also implies a lack of hormonal activity.
