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)
Men's Sexual Health: Erectile Dysfunction
Disorders, Information, Treatment, Causes, Exercise, Diet,

'It has been recently estimated that more than 152 million men worldwide experienced erectile dysfunction in 1995, and that this number will rise to approximately 322 million by 2025.' 1
Study on Erectile Dysfunction & Cardiovascular Disease
Preliminary findings from clinicians at the Research Institute of the McGill University Health Centre (MUHC), show that men with erectile dysfunction are more likely to have cardiovascular disease. Cardiovascular disease affects approximately 40,000 Canadian men annually.
"Our study suggests, that erectile dysfunction, particularly in young
men, may be an early warning sign of heart disease and stroke," says
MUHC Director of Clinical Epidemiology and lead investigator, Dr. Steven
Grover.
Dr. Grover and his colleagues evaluated more than 4 000 men. They compared
the risk of erectile dysfunction among patients with and without cardiovascular
disease. "We found that the presence of cardiovascular disease was
strongly associated with erectile dysfunction," says Dr. Grover.

Exercise & Diet Can Improve Male Sexual Function
From the website: 'In a study published in the The American Journal of Medicine, (Feb. 2007), researchers report that erectile dysfunction was significantly and independently associated with age, cardiovascular disease, diabetes, and lack of physical activity. There was an especially high prevalence of erectile dysfunction among men with hypertension and diabetes, suggesting that screening for erectile dysfunction in these patients may be warranted. Researchers from the Johns Hopkins Bloomberg School of Public Health and the Johns Hopkins Hospital analyzed data from 2126 men who participated in the 2001-2002 National Health and Nutrition Examination Survey (NHANES).
As many as 18 million men may be affected with erectile dysfunction in the United States. The recent development of effective oral medications to treat erectile dysfunction has raised awareness and furnished treatment options, however lifestyle changes like increase of physical activity, stricter dietary control and other measures for the prevention of cardiovascular disease and diabetes may prevent decrease in erectile function.

Want a Good Sex Life in Later Life? Watch your Health
A study from Harvard Health Professionals shows that chronic illness and the medications used to treat them account for many of the sexual problems of older men. Sexual dysfunction is most prevalent in men with illnesses such as diabetes, hypertension, heart disease, stroke and depression. 'The secret to preserving sexuality is to stay healthy and to build healthy relationships - and both require a series of wise choices throughout life.' (Harvey B. Simon, M.D.)

Male Sexual Function, Disorders & Treatment
From the website: 'It has been recently estimated that more than 152 million men worldwide experienced erectile dysfunction in 1995, and that this number will rise by 170 million, to approximately 322 million by the year 2025.'
This is a comprehensive study of male sexual and reproductive functioning. Topics include: normal size of the male sexual organs, aging and sexuality, role of central and peripheral neurochemicals in each stage of the sexual cycle, erections, influence of psychological factors, drugs and disease on all aspects of sexual functioning and the investigation and treatment of male sexual disorders.
Extensive discussions on newly developed strategies in psychological and behavioral counseling, drug therapy, tissue engineering, nonsurgical devices and surgical treatments for all forms of sexual disorders are also provided. Lastly, the effect of sexual dysfunction and its treatment on quality of life in affected men is addressed, along with recommendations for future research endeavors.

Study of Aging in Men & Hormones: Decrease in Sexual Desire, Arousal & Activity
Few studies have assessed the role of pituitary and gonadal hormones on
age related changes in sexual behavior in healthy men. We conducted an evaluation
of sexual function and behavior in 77 healthy married men aged 45 - 74 years.
Significant age related decreases in sexual desire, sexual arousal and activity,
and increases in erectile problems were noted.

Evolution, Human Reproduction & Fertilization: Sperm Competition & the Penis
A very interesting essay from the journal of Evolutionary Psychology on sperm competition and its role in shaping the human penis, (size, length, width, forceful ejaculation), evolutionary strategies for successful fertilization i.e. semen displacement and coagulation. On sexual intercourse and evolutionary benefits of deep penis thrusting, function of the foreskin and effects of circumcision, premature ejaculation, female reproductive strategies i.e. copulation with multiple partners, human sexual behaviour and wife rape (males having sex with their partner if suspecting them of infidelity).

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)

The free, unhampered exchange of ideas and scientific conclusions is necessary for the sound development of science, as it is in all spheres of cultural life. ... Only the individual can think, and thereby create new values for society, nay, even set up new moral standards to which the life of the community conforms.
(Albert Einstein)
