We are told that animals, through evolution, have emerged with physical and behavioural characteristics that maximise their chances of survival and reproduction.
So we can consider that human behaviour is rooted in evolution and has adaptive value.
Consider the issue of contraception. The point of sexual intercourse, from a biological perspective, is procreation, the continuation of the species. Animals aren’t doing it because they want to save their species or pass on their genes.
They are responding to their sex drive.
If it feels good, do it.
Humans, who do understand procreation, and who want to avoid pregnancy, have invented contraception. Sex without procreation.
In our mother and aunt’s day the independent woman had the pill. Like in nature, she could choose who, where and when, and had the “human” choice of avoiding pregnancy. Now, due to STDs, in particular HIV and the death sentence that is AIDS, the modern woman, our sisters and nieces, carry condoms. Same freedom of choice, different level of protection. An example of social evolution.
In the movie Fight Club, one of the characters refers to the condom as “the glass slipper of our generation – you put one on, you dance with a stranger, and you throw it away at the end of the night”.
The modern human male is still driven by the need to spread his seed as far as possible. Every man wants to be “the stud” who has slept with a lot of women. However what he does not want is a series of illegitimate children by a series of women. So he carries condoms.
