  Instagram Profile - Karene (Sexual Evolution)


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)

Human Sexual Behaviour & Activities
Information & Pictures on Intercourse Positions, Anal Sex, Foreplay, Adult Toys, Orientation & Practices (Monogamy, Polygamy)

Alfred Kinsey - Biography, Reports on Male and Female Sexual Behaviour, Studies on Homosexuality, Sex Gender and Reproduction Research InstituteMales and females do not represent two discrete populations, heterosexual and homosexual. The world is not to be divided into sheep and goats. Not all things are black nor all things white. It is a fundamental of taxonomy that nature rarely deals with discrete categories. Only the human mind invents categories and tries to force facts into separated pigeon-holes. The living world is a continuum in each and every one of its aspects. The sooner we learn this concerning human sexual behavior the sooner we shall reach a sound understanding of the realities of sex. (Alfred Kinsey, Sexual Behaviour in the Human Male, 1948)

Hello sexual people! Thanks for visiting our Philosophy of Sex pages. We have spent considerable time searching the internet for good quality sites related to Human Sexuality & Health.
Below you will find an interesting selection of articles & websites on Human Sexual Behaviour, Activities and Orientation.

Human sexual behaviour can be either individual, couple or group behaviour that results in sexual arousal. Individuals may be sexually aroused by a variety of different objects and behaviours. Some behaviours may initially seem to have little to do with procreation and are done for pleasure and / or the expression of love. However, these non procreative sexual behaviors may increase the possibility of sexual reproduction at some later time.

Human sexual behavior is driven by our biological instincts which are regulated by social customs. Thus, a certain behavior may be normal in some cultures or at some time in the past, and yet deviant in other cultures / at other times. Currently (in most countries) pedophilia, bestiality, incest and rape are considered forms of sexual abuse.

Below you will find articles on evolution and male / female sexuality, different activities and behaviour (kissing, cuddling, foreplay, oral, vaginal and anal intercourse, positions, adult toys, bondage, bdsm, bestiality, watching pornography, group fantasy, cybersex, infidelity, promiscuity etc.), orientation (bisexuality, heterosexuality, gay, lesbian, transsexual, transgender, queer) and practices (marriage, harems, monogamy, polygamy etc.). Such an eclectic list certainly portrays the wonderful diversity of human sexuality!

Our studies show that many human sexual activities and behaviours are searched frequently on the internet. Kinky activities such as MILF - mothers i'd like to fuck, hentai and beastiality (incorrect spelling) have a very high number of searches (see below). This is an interesting (and honest) insight into the sexual curiousity of humans, perhaps due to the apparent anonymity of the internet.

The top ten related searches for human sexual behaviour, activities and orientation are;
sex (250,495), porn (200,000), milf (150,000), hentai (89,346), lesbians (82,823), chat (80,000), porn video (77,739), lesbian sex (50,533), beastiality (45,000), sex positions (45,000)

We hope you find the following articles & websites interesting, informative, stimulating, useful and fun.

Human Evolution: A History of Sex

Evidence that people have been promiscuous for a long time

Lotharios everywhere will be pleased to hear that monogamy does not appear to be a natural human state. That, at least, is the conclusion of a study conducted by Michael Hammer at the University of Arizona in Tucson, and just published in Nature Genetics. By examining the DNA of living people, Dr Hammer and his colleagues have found that far fewer men than women pass their genes on to subsequent generations.

Sexual Evolution: Recent research challenges notion of Female Monogamy

For generations, biologists had assumed females to be naturally chaste, while males were renowned for their promiscuity. Now, hundreds of studies and a spate of books are challenging that conventional wisdom.
Females of many species have evolved strategies for passing on their genes that involve copulating with multiple males. Males, in turn, have adapted ways to ensure that their genes, and not those of competitors, are passed on. Understanding this co-evolution is changing our view of male and female sex roles.

What is Sexual Perversion?

From the website: 'Many conservative religious groups (i.e., Catholic church and Evangelism) see sexual perversion as a cause and as a symptom of the decay of society's moral standards. Often, conservative groups regard any sexual activity outside procreation as immoral and therefore a perversion.

... Sexual perversion is an extremely difficult concept to define. It is often defined by an individual's own perceptions, experiences and morals of what should and should not be considered a perversion. Two possible definitions are: deviation from the normal (however, what is the definition of normal?); and a descent from the ideal (what ideal and who determines it?).

Alfred Kinsey on Male Homosexuality

'The data indicates that at least 37% of the male population has some homosexual experience between the beginning of adolescence and old age. Among the males who remain unmarried until the age of 35, almost 50 % have had a homosexual experience.
It is true that there are persons in the population whose histories are exclusively heterosexual and exclusively homosexual. But the record shows that there is a considerable portion of the population whose members have combined both homosexual and heterosexual experience.'

Study of Arousal in Gay & Heterosexual Men & Women

Three decades of research on men's sexual arousal show patterns that clearly track sexual orientation - gay men overwhelmingly become sexually aroused by images of men and heterosexual men by images of women.
In contrast to men, both homosexual and heterosexual women showed a bisexual pattern of psychological as well as genital arousal. That is, heterosexual women were just as sexually aroused by watching female stimuli as by watching male stimuli, even though they prefer having sex with men rather than women.

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.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)
