I think saying its emotional is too vague. I would have to disagree. Yes womens brains work differently. Estrogen and testosterone works differently. Estrogen is best categorized as emotional (subprimal) thought, while testosterone is best categorized by precision and power (primal). But women and man are not too different other than this.

Cheating in general is bad because it lacks moral precision, and it does not matter if you are a male or female. And when it comes to having different partners, its only MORE morally correct for a man to be able to do so because how testosterone and the way genitals work, as well as the biological blueprint of the male body and the male template being polygamous. Look at stallions, tortoises. They find mates and create tribes.

When it comes to women, Their act of cheating is not what we traditionally view as "emotional", and its almost a deception to call their cheating emotional because that almost implies that its somewhat a mindless second nature (related to a current feeling), or primal instinct to be polygamous. Let me explain.

Their act of cheating is best called calculative. And the reason people say they cheat emotionally is because they are trying to describe what it means to commit an act of goal oriented fornication. Whether they are bored and looking for a new game to play with, or are hypergamous to find the best provider, It is not the same like how a man sees a sexy body and immediately gets hot and loses his mind just to ejaculate, or even worst blue balls if he does not do so. This form of primal emotion and feeling is also highlighted against the woman emotion by the post nut syndrome every man feels after ejaculation, almost as if he "returns to his senses" after doing so.

In this case the word emotion is almost a Homonym because when people think of emotions they first think of feelings. But if cheating were about feelings, then men would be take the prize for cheating emotionally because obviously being horny is one of the most powerful feeling that men constantly battle, and this feeling fits the description of what happens when a male is cheating or courting mates. But the emotion people refer to when talking about women cheating is less of a fleeting feeling and more so of a buildup of mental process and sometimes goal oriented calculations. At the very least different from the process of primal emotion men go through when cheating.

Women cheating being way worst is best described as "more" calculative, more "mental" instead of primal like how man cheat. That's the best way I can say it. I'm sot saying women do not get horny or feel sexual attraction, but to explain the slight differences between why they do.

Normally when a man cheats, its usually because of his instinct for sex. The action is the endgoal. But when a woman cheats, Is it primarily for the same reason as men? You would have to understand female nature well in order to answer that question.

There's a saying that when it comes to woman's mind about sex, everything is about sex except the act of sex itself...And vise versa for men.
