The scene is meant to show she is dominant and aggressive, not into emotional sex/emotional vulnerability, not able to connect with her sexual partners or people in her life. She is also sexual and knows what she likes/wants, takes what she likes/wants.
it's also meant to be funny, the toothbrush scene.
Cop shows and action movies and all kinds of shyt, have shown the reverse dynamic 1,000 times. Tough guy cop putting on his gun and getting dressed as delicate women cradling her breasts in the sheets begs him to stay. Tough guy cop who doesn't talk about the job. Says some kind of sarcastic but semi sweet a$$hole remark on his way out the door.
it's not meant to be rape like LOL
