Your brain is your most powerful sex organ. Here's why.

Researchers attempt to distill the science of dirty talk, submissive sexual activity, and the overall nature of arousal.

When we think of sex organs, our minds veer toward the naughty parts between our legs. But our minds should be veering to, well, our minds. The real catalyst for sexual activity is the brain — specific parts of the brain — not genitalia. That's why sexually driven language — dirty talk — is so arousing. When partners talk dirty to each other, they're stroking the right organs.


A wealth of scientific research establishes the brain's primary role in sexual activity. Sex drive, for example, originates in the hypothalamus, which is responsible for testosterone production in the testes. The amygdala, on the other hand, is a center for fear in the brain. Both brain regions strongly effect how we respond to dirty talk and sexual stimulation in general.

Because men have larger hypothalami, for instance, they have more testosterone. This explains why the male sex drive often exceeds those of females, why men tend to initiate sexual contact, and why men are less cautious about who they take on as sexual partners. Partners who seek a submissive role, on the other hand, are led more by their amygdala, one of the brain's fear centers.

Dirty talk achieves arousal because it's fine-tuned to stimulate the right parts of the brain. It feeds our need for intimate conversation and lust for sexual activity. It provides a multi-layered sexual experience that extends further than just physical touch. Dirty talk works because it's sex through suggestion, and to our brains, suggestion can be just as powerful as full-on execution.

  • A skeleton representing a man who was tossed face down into a ditch nearly 2,500 years ago with his hands bound in front of his hips was dug up during an excavation outside of London.
  • The discovery was made during a high speed rail project that has been a bonanza for archaeology, as the area is home to more than 60 ancient sites along the planned route.
  • An ornate grave of a high status individual from the Roman period and an ancient ceremonial circle were also discovered during the excavations.

In Aldous Huxley's 1932 novel “Brave New World," people aren't born from a mother's womb. Instead, embryos are grown in artificial wombs until they are brought into the world, a process called ectogenesis.

A big lesson from the ‘Oumuamua alienware controversy

Scientists should be cautious when expressing an opinion based on little more than speculation.

  • In October 2017, a strange celestial object was detected, soon to be declared our first recognized interstellar visitor.
  • The press exploded when a leading Harvard astronomer suggested the object to have been engineered by an alien civilization.
  • This is an extraordinary conclusion that was based on a faulty line of scientific reasoning. Ruling out competing hypotheses doesn't make your hypothesis right.
