Girls, boys, who cares?

So, I frequently ask myself why I'm bisexual. What makes me different than other people, whats different about me than my next door neighbor, or the kids in my math class? A lot of people say its genetics, that they're just born gay, or bi, or straight. But I feel like its a mental thing, as well. I feel that it could be connected to our upbringing, and how our parents or others around us treat the idea.
When I was a child, I had little school crushes, all on boys. I didn't really know about being gay, I didn't really think about it. When your a child, you just automatically drift towards the opposite sex, when it comes to having crushes, you know. But then I met some older kids, kids that were in high school. two of which were lesbians. That opened a new door for me, one that I hadn't known was there. My mom always taught me that it didn't matter what the person looked like, but what they were like in the inside. (Dad wasn't the prettiest man on the planet.) I really took that to heart. I think one of the reasons that I'm bisexual is because that I learned at a young age that being gay is okay, and its a possibility. And I think one of the reasons a lot of people aren't gay or bi is because they were taught that gays are bad, they learned the phrase gay before the found out the actual meaning of it. A lot of kids now use gay as a adjective to describe objects or something, not to describe someone's sexuality. Its incorrect, yes, but this is how kids are learning now, and if their first impression of it is bad, then they'll wipe out the entire idea, they'll lock that door of possibility.
I guess what I'm trying to say is that if people keep an open mind about these things, then I believe the possibility of them being bisexual or gay is more likely. I honestly believe that there could be a bit of bi in everyone. Because really, does it really matter if your boyfriend has a dick? Does it matter that your girlfriend has tits and a vagina? What really matters is that your boyfriend is a sweet guy, and he tells you he loves you. Your girlfriend clings to you like your a teddy bear, because she loves you. That's what really matters. So if your husband came home, and told you he cut his penis off, what would you do? He's the same man, is he not?
Gender is a label, just like all the other words we use to describe people. Now, I understand that we have hormones that also differentiate between genders, but even then some guys act girly, and some girls are tomboys.
So think about it! Take a long time, take it in. I didn't just decide I was going to be bisexual, it took me several years to figure it out. Think about being with that perfect person, then think about them being the same gender as you. Is it really that bad? Is it really that bad if the sweetest person in your life turns out to have boobs too? I don't think it does. Just think about it. ;)
