I uh hit my poor family with the triple threat when I was 26.
"Hey guys I'm bisexual" "Yeah, we kinda figured"
"Also I'm trans, I go by Jen now" "Wait huh-"
"Also also I'm polyamorous" "...what is that?"
Came out as bi to family in college. Came out as nonbinary to some folks like, ten years ago, but didn't do anything about it.
Not till cancer. Last year, when I went into remission, started HRT and came out fully public.
