The previous anon here thank you for loving it. I love this blog because here can I send my sexuality headcanons without a fear to people for laugh at them. Heres one more : Vivian from the Mario Rpg spinoff Paper Mario ttyd is a trans female (partialy canon, at least in japan) and bisexual. Same goes to the other partialy canon trans female of the Mario franchise Birdo.

I know it sounds silly to talk about headcanons like this for something as silly and childish as freaking SUPER MARIO games but I have had this headcanon for a while thar Luigi is (demi)bisexual biromantic and that Daisy is bisexual as well (or pan not sure). Also that Rosalina is demi or asexual biromantic...

Not silly at all. I love it.

Wesley from Wanted is a bisexual demiromantic. He is in a polyamorous relationship with, from Shame, Brandon, who's pansexual, and Sissy; an afab genderfluid, panromantic bisexual who prefers women. Brandon's boss, David, is a closeted homosexual and secretly in love with Brandon, but gets over him when he meets Wesley's ex-best friend, Barry, who is bi. Wesley's decoy is a butch, bisexual trans woman who starts a relationship with Brandon's coworker, Marianne, who is gray-ace.
