The Champion is written as pansexual, any preferences on the part of the player have to be accounted for by mental roleplay alone. You're free to imagine any given champ with whatever sort of sexual preferences and stances on relationships as you like but the game can't account for that kind of thing (seriously, it would be a coding nightmare and utter waste of time) and so your champ will get horny at the sight of giant cocks, cute little cocks, pussies of all types, pussies and cocks, subbing, power bottoming, topping, orgies with everything that moves where you're doing everything at once and hand-holding.
