Both men and women want to expeeriment. They want to pass on the best of the genes to their next generation. to some extent both men and women are cheaters.
But women are less of cheaters because they are sentimental also. Men also can be sentimental.
women cherish the sexual act. They are attached to the person who gave them happiness. Men on the contrast move on in life and in love.
once the act is over men forget it. Women replay it in their mind.
