The First Case Being a psychological case:-
The psychological case implies that a female cannot survive even a few days without having a male companion. Or it also implores that a female simply gets bored of the male fast and seeks a diff companion on a weekly basis
The Second Case Being out of pure Choice:-
In this case the female simply chooses to hop from dick to dick simply because she doesnt want to be committed to one dick.
