What is a relationship between a CIS and non binary called?

It would depend on what body the nonbinary feels more comfy in. My friend is trans nb meaning they would feel more comfortable in a male body but feels nonbinary overall. They're dating a female and their relationship is usually just called queer or straight. If they felt less dysphoric in a female's body, then it'd be called queer or lesbian. Understand? 'cause I wouldn't. This explanation sucks... Anyway I tried. I would just go with queer.
