Men and women (people) in general cheat for different and varying reasons so I feel like it's hard to quantify it. Men may do it for what are considered "slutty reasons" for example, versus a woman who may do it more often out of spite/to control their partner.
I'm female, but I don't look at it as which sex does more of the cheating. Even who is more capable of it. Rather I think that both partners are just as likely to try to screw their partner over when a relationship goes the wrong direction. "Cheating" kinda fits into the "how" when it comes to how someone may literally/not literally screw with someone. Cheating is the symptom to the problem in other words.
Women are more likely to try to cause drama domestically, like tamper/squander money or try to negatively influence child custody, whereas a man may 'one-up' the other or try to restore their 'man card' by their using their sex appeal as a tool to make their partner jealous. Just an example.
Men are more likely to have issues with commitment, so cheating sometimes is an easy 'out', will place doubt in their partner, therefore making it mirror their own lack of self-confidence in relationships. Women may cheat, but there's usually positive motivators, like emotional feedback from their partner/the person they cheated with... they may like having their partner fight to get them back, or will use the incident to punish their partner over past behavior. They are more likely to punish themselves with guilt if the emotional blackmail backfires, i.e it doesn't go their way, so it doesn't happen as frequently... I suspect. Some women just simply get a boost from their "power" over other men, that's where you get the type you describe... but I feel like from experience it's not nearly as common.
When you look at it the point of view of standard relationship problems, actual cheating is only half the picture. Maybe men are more likely to use it as a weapon too, but since women are more likely to hang onto a man because of emotional dependency, it's also possible a man may have learned how to cheat frequently in various relationships because they know how to exploit that weakness in their partners. That may make a man the more 'frequent' sex when it comes to cheating. However, I feel like both sexes cheat for both emotional and physical reasons, and that comes from the bullshit that happens in every relationship... which usually makes it about mutual, especially if the cheated on partner continues to see or 'condone' the behavior after the first incident.
