Thanks again for your thoughtful question. I agree with you that women have also cheated men all through out history. And I went back and re-worded my article to gently reflect that. But I do think women today cheat more than they did in the past, and this is why I think so.

My first point was to say that the development of birth control methods, condoms, pills, etc. has lead to women today having much more control over when to have a baby compared to in the past. And with this increased control I was arguing that it has become much easier for women in general to have sex without having to worry as much about the consequences of their actions from the standpoint of having a potential baby. In other words, women do no have to take in as much in consideration whether this particular man whom she chooses to have sex with would be a good potential caretaker in case she did get pregnant. This increased control of when to have a baby then has opened the possibilities for more and more women to explore sex simply for their own satisfaction, which among other things I believe have led to more women to cheat if they have felt unsatisfied in their relationships.

In the past, women and mothers often sacrificed their own needs for the sake of keeping their family together. Women (and of course men too) today are expecting more from their relationships. So I was arguing that the incidences of infidelity in women have increased partly due to these changes in the modern world. With increased opportunities for women to take care of themselves without depending so much on a man along with the development of birth control has lead women to cheat as much as much men.

Regarding my own cheating, I only did it when I already knew I was miserable and kind of forcing myself into a position where I either had to come clean or break up with the person.  In every case, I broke up with them.  This is, however, why I think it’s useful to distinguish between “cheating” and “having an affair.”  I think the latter is done deliberately, when you have no intention of ever confessing or ending the primary relationship, whereas the former may be a  result of what I say regarding breakups, or for some of the “ignorance” or lack of bonding that you mention.

Thanks for your comment and welcome to the community! Your point is well taken. I do agree that biology
play part in our decision making. We all have our more primal brain. And I guess if your pre-frontal cortex
where you can make logical decisions, plan, and think about the consequences of your actions is not fully developed
you might let your biology over rule your decision making. But surely you are not trying to make the argument that women
don’t have the ability think and make independent choices, are you ?
