Okay people I need help with something

Take a genderfluid person

Sometimes a girl, sometimes a boy, sometimes neither, idk whatsoever

What if they'd only feel attracted to girls? (Or to boys, whatever you want)

This really messed me up, cause like, are they straight? Bi? Gay? Pan? ;-;

Google isn't helpful either:

DalynaCentrix is thinking with me

What do you think?
