My first wife thought she was bi, but just hadn’t met “the right guy” (who was supposed to be me — nope, although we got married before she figured it out) while having several women lovers. After our divorce, more than one lesbian friend told me, “Sorry, could have warned you! Why didn’t I? Oh yeah, you two went from proposal to marriage in a couple days!” Back then (1990s) the general feeling seemed to be there were no bisexuals, just people who were confused or wanted to have “normal” relationships with the opposite sex.
Your article tells me things have gotten more nuanced! 😊
