I discovered the LGBallT subreddit recently, and to boot, I also discovered something that I think better describes my sexual orientation! So I drew this comic in LGBallT style. (Comics with LGBT themes where each gender identity and orientation is represented with a pride flag ball.)
Bisexual means attracted to more than one gender (any number over one, really). The gender of a person factors into their sense of attraction.
Pansexuals are similar to bisexuals in many respects, but they explicitly declare that they are attracted to people regardless of gender, and there is often a "gender-blind" idea to it.
Omnisexual's definition is very similar to bisexuals, except that they explicitly state that they are attracted to any/every gender. Like bisexuals, the gender of a person factors into their sense of attraction, and the "gender-blind" thing doesn't apply.
Gonna get ahead of the comments here and explain: Bisexual means attracted to more than one gender
