okay so let's radically simplify gender: a 2d plane. horizontal is male, vertical is female:

0        M




F        1

now, fill that in:

0        M
 ████████
 ████████
 ████████
 ████████
F        1

then chop off the male and neither corners a bit:

0        M
 ██▄     
 ████▄   
 ██████▄ 
 ████████
F        1

0        M
   ▄     
 ▄███▄   
 ██████▄ 
 ████████
F        1

(though it's probably more like a gradient that gets darker)

...now try to convert all that spacial bullshit to actual gender. additionally, sometimes it dips down into the third dimension (which would obviously be I҉͚̜̜̤̝͔̭͎̹̗̘͈̳̕͝ͅT̛͓̻̲͎͕̙̦̙͈̼͡͡͞ ̸̛̀͟͏̰͚͓̦̦͕̘̫ͅC҉͟҉̬̫̗̠̗̰̹̭̮͙͞O̸̵̠͎̭̣̙̱̬̞̟͓̮͔͈̩M̷͞͏̘̰͈͕̯̠͎E̵͞͏̪̯̠̖̠̻͖S̨̗̤̱̜͙̙̗̻̯̦͍͘)

additionally additionally, this analogy has helped people before: imagine the plane has a bunch of chairs on it. i'm in one of these chairs right now, but maybe next month i'll go sit in a different chair instead.
