Stage of the relationship: A clear-cut one night stand situation
You're convinced that just because she has two X-chromosomes she's interested in post-coital cuddling? In reality, she is as vexed as a womanizing frat boy when you refuse to take note of her ample hints about her a.m. dentist appointment.
Please, recognize the situation for what it is. Don't go into octopus mode and force her to pry your every limb off our body like an extraterrestrial spawn from Alien when she needs to get up to pee.
