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.

Circumcision: Health Complications, Jewish Rituals
Collection of credible articles, book reviews and information on the complications of male circumcision. Papers from doctors, academics and a jewish man.
'Meatal stenosis is the most common serious complication of penile circumcision. The stenosis may result from injury to the frenular artery with an incidence of 2% to 11%. Because of this high incidence, the risk of developing meatal stenosis needs to be included in any discussion of the risks of penile circumcision.'

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).
... What effect, if any, does the practice of surgically removing the foreskin have on the semen displacement properties of the human penis? As a consequence of removing the foreskin the circumference of the shaft posterior to the glans may be slightly reduced, causing the coronal ridge to be more pronounced and creating a larger area for semen to collect where it could be scooped back away from the cervix.
Laumann, Masi, and Zuckerman (1997) found that circumcised men masturbate more often and engage in more elaborate sexual behaviors. ... In a study of 139 women who had experienced intercourse with a number of both circumcised and uncircumcised partners, O’Hara and O’Hara (1999) found most (73%) reported that circumcised men thrust deeper and withdraw farther and thereby displace more vaginal fluids (perhaps due to reduced penile sensitivity). O’Hara and O’Hara conclude that the loss of vaginal lubrication and discomfort is 'because of the tight penile skin, the corona of the glans, which is configured like a one way valve, pulls the vaginal secretions out of the vagina when the shaft is withdrawn'. Therefore, although practiced primarily for religious and/or hygienic reasons, an unintended consequence of circumcision may be to enhance the semen displacement properties of the human penis.'

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.
