I wish there had been better bisexual representation when I was just a bit younger.
Throughout all of my highschool and college years, there was a very explicit reinforcement that bisexual people didn't really exist... that they were just these people who were denying their homosexuality or something, and probably the only reason I didn't ever really admit it to myself was because I was terrified that somehow admitting I was bi was like, some kind of step down a slippery slope, with "gay" at the finish line. It was never that I saw anything wrong with being gay, or the concept of one being gay, but when you're really young, and the rules of the adult world are slowly unfolding themselves toward you, you end up naively clinging to the rules that you're given, and in my mind, going down that path meant somehow compromising on being attracted to girls, which sounds really stupid now, but it was something I didn't want to do.
I dunno, I was also really terrified of "being bi" simply because I didn't find any of the gay men I knew particularly attractive, and I was actually really worried that if I "opened the floodgates," I might elicit unwanted sexual advances from them... which also seems like a really stupid fucking thing to worry about in retrospect. I also really liked, and still really like girls, and when your paradigm for sexual attraction is gay/straight with no middle ground, you tend to needlessly fret (am I actually gay, how do I know if I'm straight?) about dumb shit.
I dunno, I'm much more at peace with everything now, as compared to where I was when I was, say, 19, or 20, but damn I wish I'd had a better archetype for this stuff back then - It kind of sucks being a late bloomer, but I guess better late than never? If I'd had some visible role-models who could've exemplified what healthy bisexuality looked like, maybe I wouldn't have been such a stick-in-the-mud during my college years.
That's why it makes me happy that most of you guys understand how and why representation matters.
