  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.

Hello. This webpage is about understanding the biological and psychological functions of human sexual arousal. If (like most people) you want to be good at seduction it will obviously be useful to understand these more primitive evolved foundations.

Below you will find summaries of articles & websites on male & female sexual response, signs of arousal, the brain, ovulation and primate behaviour.
'Arousal' is not a popular search on the internet (desire 1,000 /day and lust 2,000 /day are more popular). Obviously people are more likely to search what arouses them e.g. porn gets 250,000 / day, ranked 2nd.

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

Definition & Signs of Human Sexual Arousal

Sexual arousal is the process and state of an animal being ready for sexual activity. Unlike most other animals, human beings of both sexes are potentially capable of sexual arousal throughout the year, therefore, there is no human mating season. What are the signs of human sexual arousal?

Sexual arousal in both genders

* Increase in breathing rate
* Increase in blood pressure
* Increase in muscle tone (myotonia)
* Increase in heart rate (tachycardia)
* Vasocongestion of the skin ('sex flush')
* Slight or extreme dilation of the pupils (though especially so with females)
* Erection of the nipples (especially upon direct stimulation)
* Release of pheromones (our natural scent)

Female sexual arousal

* Increase in breast size
* Swollen Lips
* Lubrication of the vagina
* Vasocongestion of the vaginal walls
* Clitoral tumescence and erection
* More visible venous patterns across the breasts
* Elevation of the uterus and stretching of the vagina
* Change in shape, and increase in size of, the labia majora and labia minora

Male sexual arousal

* Penile tumescence and erection
* Emission of pre-ejaculatory fluid
* Ascension and swelling of the testicles
* Tensing and thickening of the scrotum

Study of Sexual 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.

Arousal & Body Language: Power of the Eyes

Men are attracted to young healthy women because they have the best success in producing healthy offspring. Bright, white areas in a woman's eyes plus long, thick eye lashes are excellent indicators of female good health. Women know how their eye contact can activate men's hormones and interest.
Since the pupil can not be controlled consciously it is an excellent and reliable broadcaster of emotions. When the pupil is closed down to a small opening (when not in bright light) it indicates a lack of interest or something distasteful. Dilated pupils indicate high interest or desire.

Orgasms & Sexual Arousal in Women: A Study of Cardiovascular and Endocrine Alterations

This study investigated the cardiovascular, genital, and endocrine changes in women after masturbation induced orgasm.
Sexual arousal and orgasm produce a distinct pattern of neuroendocrine alterations in women, primarily inducing a long-lasting elevation in plasma prolactin concentrations. These results concur with those observed in men.

Study of the Brain while watching Pornography

By studying men watching pornographic videos, researchers in Canada have pinpointed areas of the brain that become active when the men tried to avoid being stimulated. In evolutionary terms, these regions of restraint (the prefrontal cortex) are newer than the more primitive areas where the sexual urges arise in the first place (the limbic system).

Arousal in Women, Viagra & Erotica: 'All in the Mind'

Scientists have concluded that women achieve most sexual satisfaction through the stimulation of their brain and not any other organ. After eight years of tests involving 3,000 women, Pfizer, the company behind Viagra, the little blue pill that has transformed men's sex lives, has abandoned efforts to prove that the drug works for females too.
Studies found that even though Viagra induced a greater pelvic blood flow in women. they did not feel substantially more aroused.

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)
