Additionally women are shown to be more miserable down the road the more sex they have outside of single partnerships. Women typically place more emotional values on sex while men typically place physical stimulation above their emotions, when a woman is constantly switching from partner to partner and is unable to keep one she feels as though she is unimportant as anything more than a sex object. Men don't care if they are treated as sex objects, as biologically they are inclined to spread their seed as far and wide as possible.
