I figured coming out to my mom as a bisexual wouldn't be a huge deal. I trust her a lot, and I know her to be a progressive woman; she's generally liberal, pro-choice, pro-gay marriage, she even played on a women's flag football team for twenty years where the vast majority of the members, her friends, were lesbians.
So I came out to her over Thanksgiving. The reaction was, while not the opposite of what I expected, still pretty surprising. It turns out my mom doesn't believe bisexuality exists. Its not that she is anti-bi, she just believes its a “phase” and that I'll “have to pick sides eventually.” She wasn't angry, and didn't treat me differently after I told her, but it was as though I had mentioned that I was having trouble deciding on a major; my bisexuality was something to work through, figure out, and decide.
The most frustrating part of the experience is how often I get similar reactions from people to the concept of bisexuality. Look, people: being bi isn't a stage in life that I'm going through. When I finally settle down with a guy or a girl, I won't suddenly be straight or lesbian. I'll have decided upon a person, not a gender. To me, that's why being bi is: having the ability to fall for people, regardless of their sex. Lyrics always say it best: “I just don't care whats under there.”
