I so very rarely play characters that fall at the extremes of the Kinsey scale.  My typical go-to for characters is omnisexual, because that's what I am in real life and I feel the most comfortable in that space.  I like the fact that it makes literally anyone open for a possible romantic or sexual pairing, because I hate having my options limited.  -giggles.-  So, even playing canon characters, I'm gonna try for a bisexual, pansexual or omnisexual option, just because that way I don't have to be all huffy because the awesome-ass character with the genius player isn't the right gender.
