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)
Intra Uterine Device (IUD)
Birth Control, Contraception, Female Reproductive System
Types of Intra Uterine Devices (IUD), How they Work
From the website: 'The intrauterine device (IUD) is a long term birth control method. An IUD is a small, T shaped plastic device that is wrapped in copper or contains hormones. The IUD is inserted into your uterus by your health professional. A plastic string tied to the end of the IUD hangs down through the cervix into the vagina. You can check that the IUD is in place by feeling for this string. The string is also used by a health professional to remove the IUD.
Types
* The Levonorgestrel (Lng) IUD, also known as Mirena, releases levonorgestrel,
which is a form of progestin. This IUD appears to be slightly more effective
at preventing pregnancy than the copper IUD. It is effective for at least
5 years.
* The most commonly used IUD is the Copper T 380-A. Copper wire is wound
around the stem of the T-shaped IUD. The Copper T 380-A can stay in place
for at least 10 years and is a highly effective form of contraception.
How it works
Both types of IUD prevent fertilization of the egg by damaging or killing sperm. The IUD also affects the uterine lining (where a fertilized egg would implant and grow).
* LNg IUD. This IUD prevents fertilization by damaging or killing sperm
and making the mucus in the cervix thick and sticky, so sperm can't get
through to the uterus. It also keeps the lining of the uterus (endometrium)
from growing very thick. This makes the lining a poor place for a fertilized
egg to implant and grow.
* Copper IUD. Copper is toxic to sperm. It makes the uterus and fallopian
tubes produce fluid that kills sperm. This fluid contains white blood cells,
copper ions, enzymes, and prostaglandins.'

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)
