No.
Women cheat like men. IMO, I don't believe that women are "better" cheaters. To be a better cheater, one must master the art of emotionally detaching oneself from people they sleep with, so how are women better cheaters when they are more likely to become emotionally attached to their sexual partners?
BTW, I am not saying that there aren't any women who are good at getting away with cheating. I am saying that women are not universally better at cheating. Men be having whole side families w/o their spouse knowing just like women have side babies w/o their husbsnds knowing. Both men and women can be good or bad at cheating. It is on an individual and circumstantial basis.
Next, I believe women are more likely to not get caught cheating because people ass-u-me that they are loyal by default. They are more than likely given the benefit of the doubt when it comes to fidelity.
Therefore, once someone is given the benefit of the doubt, they are given a green light to do dirt because they are not expected or assumed to do dirt.
In all, people who cheat always leave cues, some blatant and others more subtle. People need to be keen to people's body language, mannerisms, behavior, etc. In essence, if you peep game, you will eventually find out if someone is cheating on you or not.
