I like to play certain characters as a set gender. (my PC is generally female)

Bailey

• always male.

Whitney

• always male, but I don't mind a female Whitney either (in fanfic). PC and Whitney's dynamic changes drastically depending on gender in my eyes.
• if they're both the same gender, there is an underlying theme of internalised homophobia (primarily from Whitney). I always HC Whitney as someone who cares way too much about their public image. chalk it up to the dynamics of secondary school or whatever, but they're just not mature enough to filter the noise of others. It will change when they're older.
• I also generally the brutality of a male Whitney when playing with female PC.

Kylar

• can be either male or female.
• male kylar is giving reddit mod/yandere creep
• female kylar is a girlfailure femcel

Sydney

• also can be either male or female. i do prefer a female Sydney though. Again, the theme of religious guilt and internalised homophobia apply.
• tons of compulsory heterosexuality beliefs too.

Robin

• it depends. I personally like Robin as female more, but male Robin is also fun for storyline purposes as well. I really like the idea of Robin being a cuck.

Alex

• male always. the 'nice guy' trope. i just can't see Alex as female.

Avery

• I switch between female and male Avery. the whole mommy and daddy dynamic is really hot and it completely changes depending on PC's gender.
