his parents wanted him to get married so badly that even if he were bi he would never entertain the notion. but he isn't at least, so. only mans for benedict
barrow is heteroflexible, I think he has had subtle little crushes on men before that he won't interrogate and would potentially be open to Fooling Around as long as he's not receiving, if you will. but his heart is mainly with the ladies
Teren is pretty solidly bi, she has had serious relationships with men and women. she herself is intersex but identifies as a woman. she doesn't like to receive much physical attention bc she finds it painful/uncomfortable so any sexual involvement tends to be one-sided (which she doesn't mind, and finds power in it etc)
and Fifi is a little more male-leaning just in the like.... cultural sense I think, but has no serious relationship experience with women so it's a bit of a tossup. she finds both attractive and would be more inclined toward women nowadays
