Previous studies have shown that the sense that the brain is “sexy” is a combination of cognition, emotion and physical processes. However, studying sexual behavior, which is a very personal thing, has many challenges.
One study using data from the Yahoo group has examined abnormal sexual preferences among 5,000 online users, and has been directed not only to parts of the human body, but to things such as shoes and headphones related to the body. It turned out that a lot of fetism exists.
Particularly popular were body fluids, specific body types, and feet and toes. Fetism for feet and toes was large, accounting for 47% of the total fetism.
The mechanism of the brain is largely involved in foot fetishism. When mapping where each part of the body and the corresponding brain site is located, the toes, toes, and genitals are located very near.
One study that examined the relationship between libido and brain location examined people with epilepsy who had sexual arousal on safety pins.
When a part of the patient's brain was removed, the seizures disappeared, and the libido on the safety pins also disappeared.
The tendency for sexual fantasy is said to be created at an early age of people, where synapse formation and neurogenesis take place. Sexual imprinting takes place during this time of learning 'desired traits as companions' as other animals do.
Studies conducted in the past have shown that women raised as adoptives choose as marriage partners those with facial features very similar to their adopted fathers.
Also, women who say they have emotionally cooperative relationships with their fathers have been shown to choose men with similar fathers as companions, compared to women who have negative relationships with their fathers.
Such 'sexual imprinting' can happen to things. In one study using rats, rats with no experience of mating were divided into 'jacketed groups' and 'non-jacketed groups', and each rat was mated.
Then, when the rats were sexually matured, the rats in the non-jacketed group mated regardless of the jacket, while the rats in the jacketed group gained sexual excitement without the jacket It was not done. Even if you use other things, it seems that similar results will be obtained in such research.
This explains why people with fetishism against leather can not get sexual excitement without leather.
In another study using rats, a male rat's child was divided into a lemon-bed and a non-scented odor-free bed, and then 'lemon' as the first mating partner. We gave two options of 'scented female' and 'odorless female'.
Then, rats grown in an odorless bed preferred both females, while males who were placed in a bed scented with lemon tended to prefer females scented with lemon about.
However, such specific desires and preferences seem to be abolished by blocking the action of endorphins on opioid receptors in the brain when the drug
Not only rats but also human beings have been studied for sexual desire, but as a result of the research, it is also true that many sexual preferences have been considered as mental disorders.
However, specific sexual desire and fetishism are unique experiences only for the person, and in modern science it is shown that having fetism etc. is normal as a human being.
