On tonight’s show, Kristie revealed that she has a fetish – to be dominated in the bedroom.

It got us thinking, why do we have fetishes?

“I’ve heard of everything from feet to dirt to cars,” says Justin Lehmiller, Ph.D., a sex educator and research psychologist at Harvard University. “Pretty much anything you can think of, someone out there probably has sexual associations attached to it.”

A Fetish is when a person derives strong sexual arousal from some non-human object, a non-genital body part, or a bodily secretion.

The most popular fetishes, now and in the past, centre on body parts – especially feet or toes (ewwww).

There are four theories as to why we have a fetish?

1. The brain-overlap theory – Apparently the areas of your brain that control your sexual body parts are located alongside the region that manages your feet……. TRUE STORY.

2. The Pavlovian Theory – In the 60s, research showed a group of men were shown images of naked women alongside boots…eventually the men were turned on by the boots… Although, apparently you can have sexual impulses towards random objects.

3. The gross-out theory – Apparently…and we cannot believe this… but… when sexually aroused…your disgust impulse weakens.

4. The Pain Theory – Research has shown sexual pleasure and pain involve the release of the same brain chemicals. These ties may help form connections.
