When a character like Wyll who has a past relationship with a female cambion, and will hit on Lae'zel and Shadowheart, offers to bunk with my male dwarf berserker, it hits an odd note for me.
I believe it's called either heteroflexibility or polysexuality. However, compared to our (pretty mundane) world, FR has a whole additional dimension to it - species. Specifically, sentient ones. If he somehow managed it with a cambion, an affair with a male dwarf berserker should be "almost straight".
