A list of the most likely sexualities of every league champ. Using Neutral for anything without sexual preferences instead of asexual, since it would get crossed with the biological definition.
Aatrox: Pansexual, most likely doesn't care about gender, just the sexual thrill of war (and kinky BDSM stuff)
Ahri: Bisexual, we've ALL seen enough art to know this
Akali: Straight, she got them eyes for Shen and Zed you know?
Amumu: Neutral, died too young, most dead champs wouldn't have a preference forwarning
Anivia: Asexual, Anivia is a strong black woman who ain't need no hawk
Annie: fuk off %%%%s
Ashe: Straight, her arrow flies straight, just like her sexuality
Azir: Straight, into some weird sivir incest tho, reminds him of his late-wife
Blitzcrank: Neutral, he only has feelings for different champions, but no romantic ones, good at helping others though
Brand: Neutral, after he was no longer human, he has no need for such feelings
Braum: Homosexual, He prefers the company of men like Gragas and Tryndamere
Caitlyn: Lesbian, Has a thing with Vi
Cassiopeia: Straight, she isn't as socialable anymore, but she still prefers men, and with her new snake body, she has found she can do some interesting things with her tail~ She does have a bit of a thing for Sivir, something involving lots of toys and prodding, probably just some hatefucking (pls no banarino)
Cho'gath: Unknown. it is unknown if he needs to reproduce, or if he wants to, all we really know is he wants to eat.
Corki: Homosexual, he has a small crush on Heimerdinger, it's why he followed him to the League

Dr.Mundo: Homosexual: "Mundo go this way!"
Draven: Too Narcissistic to have a normal sexuality, his fetish tho is self-cest.
