A woman that has a high body count will never show those signs after sex, she has given out her body so many times that her body doesn't even hold any worth and power anymore. That's why a woman can have sex with you today and then ghost or pull back tomorrow.
Don't be the guy to start chasing her or asking her simp questions like "Why are you ignoring me" "was the sex bad", just understand she's a 304 and since you've had sex with her, you've conquered her. Let the streets cover her tab and move on to the next.
