Common opinion is that men are genetically predetermined to seek a multitude of sexual partners. That is simple math. Genes in men have a better chance to reproduce themselves many times over if the man sleeps with a lot of women.
Furthermore, as many men are descendants of men who were seeking multiple opportunities and sired children with many woman, they may have inherited the character trait of seeking many women.
Common opinion, on the other hand, is that women do not seek multiple partners as much as men do. Common opinion suggests that for women, it is the most promising procreative strategy to bind a man as protector of children they have together.
If only things were as simple as simple math suggests.
First of all, if promiscuity is a character trait that is genetically spread by promiscuous men, where is the guarantee that it is carried over only to male descendants?
And then, is the reproductive success of women who have sex only with a man who is a long-term protector and provider really greater?
The female reproductive physiology provides a procreative advantage to women who sleep with several or even many men.
The human vagina is designed to store sperm for several days. It can perfectly store the sperm of several men, not just that of a steady partner.
And when the egg descends from the ovary to the uterus, the sperms, whether of one man or several, compete with each other in a swimming race to the egg.
The strongest sperm cell will win, and is likely to result in a healthy child.
What makes a woman agree to a certain man as steady partner, such as power and attractiveness, are no guarantee for healthy sperm. But competition between the semen of several men, or even many men, indeed increases the likelihood of an egg being fertilized by a healthy sperm.
Of course, the behavior of humans, whether male or female, is determined not only by genetic factors. Cultural rules play a major role, for females even more than for males. So, female sexual behavior and female sexual fantasies may be quite divergent.
All the women with whom I had a close intimate relationship for some time revealed a preference for porn videos depicting one woman with several men.
No, they did not actually pursue such adventures. There are substantial personal and cultural barriers. But that the sexuality of women is directed only to a steady partner is probably wishful thinking. Of men.
