  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)

Anal Sex
Evolution & Health Benefits to Prostate, the Male G Spot, Sharing Diseases, A Guide for Men & Women, Gay, Ass Orgasm, Statistics

Vintage woman showing off her sexy bottomHi! Thanks for visiting our evolutionary philosophy of human sexuality pages. We are currently researching good quality sites relating to our biological and cultural sexual evolution - as a way of collecting and presenting the most important / latest knowledge and research.

Below you will find summaries of articles & websites on Anal Sex i.e. studies on human sexuality, evolution & health, male g spot, statistics on prevalence, how to guide, history, behaviour in different cultures and species.

Anal sex is reasonably popular on the internet. The 'taboo' factor probably enhances the interest, also that it is a practice both heterosexual and gay couples can enjoy.

Some things to consider (for future research).

The male prostate is stimulated during anal sex (which is very pleasurable to the man). Does massaging / stimulating the prostate reduce the incidence of prostate cancer?

One of the evolved functions of sex (besides reproduction) is the sharing of diseases. It is interesting to consider the receptivity of the anus along with the mouth, vagina and foreskin. Are different diseases and molecules permeable in the anus?

The anus is full of sensitive, responsive nerve endings and blood vessels. Have we evolved to find anal sex pleasurable?

Why then does the anus not lubricate when stimulated, like the vagina?

Benzene (a common solvent and known toxin of the immune system) is found in most sexual lubricants. Is there a higher incidence of benzene related diseases amongst gay men? This article on Benzene, Lubrication & AIDS suggests that AIDS is not caused by the HIV virus, but rather by toxins in our environment, in particular benzene.

Dominance and submission between gay males. The penetrator is the dominant position, the penetratee (may be) submitting to pain. Does the dominant male 'mark' the submissive with his semen? Is dominance a cultural myth?

We hope you find the following websites fun and useful. I have read 'The Ultimate Guide to Anal Sex for Women' by Tristan Taormino and plan to write out quotes from the book. If anyone has pictures of male to male anal sex I could use, please write to me. I only have access to vintage erotica women - I'm not purposely discriminating!

Anal Sex is Increasingly Popular with Heterosexuals

Vintage nude woman showing her bare bottomEvery couple of years, another once-scandalous sex taboo starts making its way toward the commonplace. A decade ago, blow jobs were what people whispered about; then three-ways became the naughty bedroom act. Now, it’s anal sex - but according to the Centers for Disease Control’s National Survey of Family Growth, it’s rapidly becoming a regular feature of hetero couples’ horizontal activities.

The survey, released last year, showed that 38.2 percent of men between 20 and 39 and 32.6 percent of women ages 18 to 44 engage in heterosexual anal sex. Compare that with the CDC’s 1992 National Health and Social Life survey, which found that only 25.6 percent of men 18 to 59 and 20.4 percent of women 18 to 59 indulged in it.

... Though the report is chock-full of all kinds of straight, gay, and lesbian sex in fairly graphic detail, there’s absolutely no research on female-to-male anal play. ... But the newly discovered anti-cancer benefits of prostate stimulation are giving straight guys - a legitimate excuse to be more, shall we say, open to exploration. And men’s magazines, which until recently discussed anal sex only in terms of how to trick a girlfriend into giving it up, now publish articles on the Aneros - the doctor created, FDA approved prostate stimulator - and the male G-spot, a.k.a. the P-spot, a.k.a. the He-spot.

Anal Intercourse: Practice and Pleasure. A Sex Guide for Men & Women

Cheeky vintage woman is looking for some anal sex!From the website: 'While upwards of 50% of women are reported to have tried anal intercourse, only about 10% engage in it regularly. The reason being, many find it uncomfortable or painful. ... When done correctly, anal intercourse can be very enjoyable for both partners. It also appears to be gaining in popularity. The 10% who do engage in anal intercourse regularly may do so for many reasons. They may find the intense sensations that some women find painful to be very pleasurable. Others may not have access to birth control, or they do not trust it, some find the naughtiness of it a major turn on. Women that like the idea of anal intercourse should not give up on it if they found it to be uncomfortable or painful in the past.

... The first steps involve anal massage. Usually when the anus if first touched it contracts, preventing entry. You need to get the anal muscles to relax prior to any insertion. Lubricate the anus with a water based lubricant or saliva. Gently massage the anal ring with light circular strokes. Push gently in on the anal ring, but do not penetrate the anus. With time you should feel the muscles relax and the anus open up. Often times it helps to perform the anal massage while caressing the vulva or performing cunnilingus.

Once a woman is accustomed to anal stimulation, and you are aware of when her anus is relaxed, you can start exploring anal penetration. The anus and rectum are very delicate so be sure to only insert smooth objects that do not have any sharp edges. ... In the beginning you just want to insert your finger without moving it around. You want to condition her to the feeling of something being in her anus. She will likely enjoy the feeling of something being in her anus when she experiences orgasm.

By the time you consider anal intercourse, she should be so accustomed to anal penetration that she has no apprehensions at all. She needs to welcome the idea of your penis entering her anus. Prepare her anus with your fingers and butt plugs first. Go slow.



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)
