Introduction / Summary (2018): Hello and welcome to our Sexuality pages. While this is not a pornographic site, it is provocative - founded upon what people search on the Internet (which is very interesting!). We then relate this to our biological and cultural evolution.
Sex is obviously important to people - and if you want to improve your sexual relationships then knowing the truth about our human evolution is the best foundation. By opening our minds to a greater diversity of behaviors, this knowledge will help you creatively cultivate healthy pleasurable moral attitudes and sexy smutty relationships (free from religious guilt & cultural myths).
Support an open honest discussion on the truth of our sexual evolution and behaviour. If you support sex positive, moral, informed sexual behaviour please share this knowledge. (These pages have a diverse collection of fascinating information relating to our human sexual evolution so people will appreciate it - see our 'nice letters' page!).
Sincerely, Karene.
"It is not enough to conquer; one must learn to seduce." (Voltaire) - "Desire is the essence of a man." (Spinoza)

Introduction
From an evolutionary perspective it is interesting to consider the occurrence of group sex in our tribal ancestry and how this behaviour has continued today.
The popularity of pornography shows that humans are highly visual creatures who become aroused by watching other humans have sex. Our ancestors probably learnt a lot of sexual behaviour through watching and participation (we moderns now watch pornography).
Group sex also offers health benefits for males and females. For example, by having sex with multiple partners, females are able to select the best possible sperm. These are some ideas I will be further exploring and researching for this webpage.
See our webpage on Evolution & Promiscuity for more information.

Evolution and Group Sex: Successful Sex Strategy to be Last in Line
The early bird might get the worm, but the last in line makes the baby. From bonobo chimpanzees to fruit flies, many female animals mate with multiple partners that often queue up for the event. Studies have shown that the the last male to mate with a female is the most successful at impregnating her.
The last male can take advantage of a more 'sperm-friendly' environment created by males that have copulated before him, according to a new model put forth by David Hosken and David Hodgson of the University of Exeter in the United Kingdom.
“We know that the reproductive tract in females can be a nasty place
for sperm,” said Hodgson. The acidity can kill many sperm, and scientists
think some females’ immune systems attack sperm as a 'foreign object'.
The seminal fluid in a male’s ejaculate helps to buffer the
acidity, creating more viable conditions for sperm. By waiting
in line, males could exploit the ejaculate from other males, giving their
sperm a cushy ride into the female’s uterus to fertilize eggs.
Going last also means the male could lower the amount of sperm in his ejaculate
since there’s a higher probability of that sperm being successful.
Producing sperm is a costly investment and has been shown to require a good
chunk of an animal’s resting energy. “They may be able to adjust
their behavior and their investment in ejaculate to maximize their probability
of being a father and minimizing their expenditure of resources,”
Hodgson said.

Analyse any human emotion, no matter how far it may be removed from the sphere of sex, and you are sure to discover somewhere the primal impulse, to which life owes its perpetuation. ... The primitive stages can always be re-established; the primitive mind is, in the fullest meaning of the word, imperishable. ... Mans most disagreeable habits and idiosyncrasies, his deceit, his cowardice, his lack of reverence, are engendered by his incomplete adjustment to a complicated civilisation. It is the result of the conflict between our instincts and our culture. (Sigmund Freud)
