Why do we have sex? Why do human beings put so much effort into having it? The basic answer would be because it feels pleasurable. Yes that is true sex can be quite a pleasurable sensation, but there are many pleasurable things like eating a piece of chocolate or getting a nice soothing massage, but yet we don’t put anywhere near the amount of time and effort to do these things as put towards having sex. Another answer is for the purpose of reproduction, but with the plethora of birth control oppositions (birth control pills, condoms, etc) is that really a viable reason why most people have for having sex particularly in the western world.
What is the purpose of sex, easy enough to answer it is the mechanism that organisms use to propagate its genes into the next generation(well at least half) and why do organisms( multi-cellular organisms such mammals, fish, and birds) use this method? Well, some have theorized that it helps bolster their progenies immune system by having shared its genetic information from two genetically distinct parents. Currents theories place the emergence of sex around five hundred millions years ago.
All life purpose on this planet earth is to reproduce( as nihilistic as that sounds) and it is no different for humans. Our urge to have sex is a by-product of ions of evolutionary history. Our ability to discriminate between sexual partners under the guise of physical attraction is also a by-product of our evolutionary history. People who are physically attractive are supposed to have a good immune system so the theory goes.
And what about the differences between the sexes when it comes towards their attitudes about. Anyone who has dealings with both men and women would discover their attitudes towards sex are decisively different. While men are more prone to sexual escapades and seem to be less discriminatory when comes to who they have sex with. Women are generally more coy. This makes since when you realize the two sex don’t share the same burden when it comes to sex, i.e women get pregnant and will take the brunt of the child rearing so it makes sense for them to be the more prejudicial who they copulate with. Men, on the other hand, are programmed to have sex with as many partners as possible(if they actually choose to do this, is their own choice of course). Need proof on how promiscuous men can be, gay men, are a perfect example their ability to have sometimes hundreds of sexual partners is because of course they are not inhibited by women’s natural coyness.
So back to my original argument on why have sex. To be more emotionally attach to somebody, reasonable argument, your brain those release certain chemical that almost make you more attach to the person you are having sex with(evidence suggest this is more true for women than it is for men), but a lot of people hookup all the time, sometimes even having one night stands. Can you really be emotionally attached to a person you are minimally familiar with, and what about the countless women who give up their bodies to alpha males(i.e athletes, rappers, politician, and other men of statues) can you really say these women love these men, perhaps on a very superficial level?
Humans potency to have sex is nothing more than just evolutionary mechanisms put in place to make sure we are acting on evolutionary obligations to propagate genes into the next generation.
