I received an e-mail from a woman mad about the strategy of many men in virtual conquests. Many of them send hundreds of e-mails, evidently privileging quantity and not necessarily quality of contacts. Meanwhile, women are much more careful in their communication, treating every correspondence in a very particular way. When she mentioned that, I immediately associated this difference in virtual behavior between men and women with the fact that men produce trillions of fertile spermatozoids all through their lives. Michael Gurian, an American social philosopher and therapist, collaborates in this reflection helping us to understand the differences in behavior between the genders. To him, men live a sort of reproductive compulsion where they need to ejaculate as much as they can. Women´s biology, on the other hand, does not ground in the creation of constant fertility. They generate around 300 fertile eggs in a life time. Comparing to the trillions of spermatozoids, a fertile egg is rare. Therefore, sexual promiscuity is not part of feminine nature as much as it is for men. For her fertile period happens only a few days a month, having a companion by her side guarantees the breeder she needs. Of course besides biology there are other influences such as cultural and psychological that also determine human behavior. Fortunately, the human being has the great capacity to go beyond its nature, making it possible to control or discipline some undesirable behaviors. Hence, before judging, criticizing or demanding the opposite sex to behave in a way you think is the right one, remember the mind of a woman or a man is a kind of a black box with many mysteries to be revealed. It is easier to seduce someone from the opposite sex when we understand them better. So I advise women to let men use their spam method and maybe one of those e-mails will reach your mail box. After that, try to allure him with your female wisdom.
