A woman can love many men at the same time, as well as kids, and even animals. Love is not a gender or person specific emotion, but it is just an emotion. Love who you want, but women are naturally submissive, and if you are with two men at the same time, it will create conflicts that you cannot resolve. This is why polygyny is common, and polyandry is almost unheard of. One works and the other doesn’t because of the personality and natural inclination of how people are created.
