It is commonly stated in the Manosphere that women are more affected by sleeping with multiple fellas compared to the other way around. And by more affected, it is meant in a negative manner; that is, they are less able to bond with men as their n-count increases. A friend attended Lutheran high school, where he was taught the “sticky tape” analogy; where the more times a piece of tape is removed and reused, the less sticky it will be.
But does this have such a strong effect on women? Perhaps it starts with the concepts of vulnerability and investment. A woman who has just been impregnated will be vulnerable for the initial nine months, and then years beyond. She would like protection and help during this time. Furthermore, the nine month investment in her child is substantial; she would like to have the extra resources needed to make it pay off in the long run. Latching onto the fella who did the deed would seem to be a logical strategy. Feelings of attachment and loyalty to him ideally would make him reciprocate. It has not always worked, but it is worth a try.
As women sleep with lots of different men, this attachment response is triggered many times anew. Like a child listening to a favorite same song over and over again, it has less effect with each iteration. Eventually, it becomes irritating. Furthermore, this attachment response gets associated with men moving on, and the negativity attached to that. From a behavioral psychology perspective, it becomes something that one perhaps wants to avoid.
Ladies — destroy it at your own risk
