I've been reading TV tropes a lot and just had some thoughts on bisexual characters.
I love bisexual characters. You can do anything with them! You're not restricted by the sex of the remaining characters; ANY new associates could become lovers, they're just so handy!
In real, true life, I believe everybody is a little bit bi. No matter how straight or gay you think you are, there is a person of the same/slash opposite sex that makes you sit back and say 'Yeah, I'd hit that.' I got my first taste in Basic Training. Ironic, given that my best friend in high school was bisexual and I didn't feel anything for her - aside from friendship. There was a girl in my training flight that had the most beautiful breasts. I mean; just . . . like a marble statue; not too big, not too small, perfect porcelain skin and there's me in the showers going 'Fucking peachy time to find out I'm bi!'
This was the early days of 'don't ask, don't tell'; technically
