Sex!!! Part 6 – the female orgasm

Posted on by Opher

Males have a puny orgasm. The female orgasm is thirty times greater.

There are good evolutionary reasons for this.

Firstly it is a good idea to exhaust the female so that she lies on her back for a period of time. This allows the sperm to be activated and swim out of the vagina into the relative safety of the uterus. If females got up and started walking about straight after sex then the sperm would end up on the floor.
Secondly the contractions of the uterus actively suck the sperm up into the uterus.

Hence it is a good idea for the male to come first and deposit the sperm prior to the female reaching an orgasm!

Evolution is a wondrous thing!!

The problem is that it has become too effective. Humans are no longer subjected to enough selection pressure. We have killed our predators, prevented disease and ensured lots of food and water. Hence we are producing more babies than we need and the population is spiralling out of control.

We need to put this right with intelligence.

Read about the effects of overpopulation in my book Anthropocene Apocalypse.

Sex!!! Part 4 – A woman’s choice.

Women choose who to have sex with!

Women can only have a limited number of children.
Men can father thousands.

Women make themselves attractive to lure in as many males as possible and then select which is the highest status male available.

Men home in on females and choose the highest status available. They are not so choosey.

Women are selecting mates for their genes. They want a high status male with good genes to join with their own so that their children have better survival opportunities. Women look for quality.

Men look for quantity. The more women they can impregnate the most chance they have of getting children (genes) into the next gene pool.

Sex!!! Part 2

Fish have a common cloaca. The common cloaca is a chamber into which faeces, urine, sperm and eggs are all passed to be removed from the body. A common cloaca is not a problem for aquatic animals. Sexual reproduction is where gametes, sperm and eggs, join to form a zygote which develops into a new organism. Sexual reproduction, unlike asexual reproduction, enables variation. Variation is a good thing because it allows organisms to adapt to changing environments. Hence most organisms use sexual reproduction. Sexual reproduction is very easy in water. The female fish deposits her eggs on the river or sea bed. The male fish swims over the eggs and squirts sperm over them. The sperm swim through the water to fertilise the eggs. Easy!! This is the result of sex:
