I'm going to tell a girl to stop talking after we had sex
How will you tell her?
I'm going to tell her to shut the fuck up and that I don't want to hear any shit out of her
Wat you are doing is a rude and frankly threatening thing to treat someone. Talking after sex should be time for emotional bonding.
It's called a fuck buddy and I don't need emotional bonding.
It's fine to not want to talk to someone, but it sounds like your friend is looking for some level of emotional bonding.  You should be clear about what you want in your relationship if you want to keep seeing her, because it isn't fair to treat her so callously.
