It won't be news to tell you that back in the day, men used to be the biggest cheaters but nowadays, the tides have turned and women are the least loyal ones. What I'd like to talk about is: who do they cheat with?
For men it's really simple. They have sex with whoever they can. That's a little too bold of course, but what I mean is: it's not easy for a man to have sex without a commitment. Of course it is for a small percentage (the all to famous, and also hated, alpha male) it is. But most men don't just get sex thrown at them. So in most cases, they cheat because they feel so lucky that a woman is offering him sex without commitment, since he has a girlfriend or wife. So who he cheats with is pretty unspecific. If he does have a choice, the answer is even more simple: the hottest one.
Women are more complex about choosing who they cheat with. First of all, it's a lot easier for a woman to simply have sex, especially when she's good looking. One thing seems to be the biggest attraction to us though when it comes to sex: dominance. The man she would bang behind her partners back is one that she sees as more dominant than her husband. In other words, superior. The guys most women cheat with are the following:
-The husband's/boyfriend's boss. It's a stereotype but it does seem to hold a lot of truth. There are an awful lot of stories of bosses letting their employee work overtime so they can go over to the man's house and take over their role to fulfill the wife's needs. I myself have seen this situation with my parents and my dad's boss when I was young, and it wasn't just one time. Women seem to get aroused by a man who orders around their own husband, even if they love their husband and the boss is being a dick to him. When it comes to sex, dominance seems to be more important than love for many women.
-The high school bully. Believe it or not, most girls in high school loose their virginity to the type of guy that bullies others. A lot of girls have a boyfriend but are not sexually active. They often loose their virginity to someone else though, and the boyfriend won't be pleased to find out who. Mostly the relationship ends at that point anyway. Bullies tend to show more confidence and masculinity than the average, sexually unexperienced high school boy.
-The rival. This is a painful one. Many guys have a friend, who they also kind of hate. He has a lot in common but seems to be slightly better at everything. To a girl, this is kind of an upgrade to her boyfriend. He seems to be in competition with him but always comes out on top.
So these are the most common guys a girl cheats with and they al show a certain dominance to her own partner.
