I'm reading the book called "Cupid's poison arrow", which revolves around a rather simple assumption: most mammals, including humans have a genetic program that is responsible for ever increasing dissatisfaction with a mate after intercourse with orgasm.
The book proceeds to give a number of examples, here's what I remember:
- Coolidge effect, where libido is revived upon exposure to a novel, receptive partner.
- Male rate copulating on average 8 times with a receptive female before losing interest
- Sexual satiety setting off a 14-15 day hormonal cycle where [a male rat] would lose all interest in a partner
The book contains a large amount of anecdotal evidence of humans experiencing negative outlook on their partner after orgasmic intercourse, with more intense intercourse producing more intense dissatisfaction.
The author proceeds to formulate a hypothesis that humans and other mammals have a genetic program that fosters sepratation between mates and seeking of a novel mate as a mechanism to promote more genetic diversity in offspring (as opposed to monogamy)
Is there a scientific basis for such claims - do mammals have a mechanism that draws them apart after intercourse or sexual satiety is achieved?
