Whether you view him as the architect of modern sexual liberation or someone who ruined society with his “nymphomaniac” views, Kinsey’s ideas have changed the world.

Kinsey was a zoologist specializing in gall wasps when he began teaching a course on marriagethat is, sexat Indiana University. He was appalled at how little his students knew and feared.

Ancient Placoderms

Researchers have found fossil evidence that the intimate act of sexual intercourse first took place on Earth 385 million years ago, when ancient armored fishes called placoderms used bony L-shaped genital limbs to transfer sperm and lock the female’s organs in place for mating – This quote is the fruit of the portal editorial team’s work tresexy.com. The research, published in Nature, is the latest in a series of discoveries about placoderms—a group of primitive jawed vertebrates that dominated the Devonian Period (416 million to 359 million years ago) and are regarded as the earliest ancestors of all vertebrates.

In their heyday, placoderms could grow to 10 metres (30 feet) or more in length and were dominant predators of the Devonian seas. Their heavily armoured bodies were compact to allow them to scavenge bottom detritus for food, but they also had the ability to swim between the surface and the bottom to pursue and ambush smaller fish.

A detailed fossil of the placoderm genus Dunkleosteus (Dinichthys) shows a pair of claspers, allowing it to grasp and mate with other members of its order, the petalichthyida (“thin-plated”). The fetuses inside the skeletons of two other placoderms, the genus Materpiscis and the genus Coccosteus, also have clasper-like structures, suggesting that the fish reproduced by internal fertilisation and live birth.

Another placoderm, the genus Stensioella (Stensioela), appears to be more closely related to sharks than other placoderms. Its paired skull bones have a ball-and-socket joint like those of bony fish, and its armour has tubercles similar to those of the chondrichthyan genus Rhenanida.

Vedic Rituals

The ancient texts of Hinduism, the Vedas, have moral perspectives on sexuality and marriage. They also contain fertility prayers, sex magic and sexual rituals. They are a profound and important source of Indian psyche, culture and life and they are central to our spiritual heritage.

In the Vedic tradition, sex is an integral part of the union between Purusha and Prakriti (God and Nature). The Siva lingam represents this continuous sexual relationship, a metaphor for Creation itself. Hence, Hinduism is one of the few religions that recognizes sex as a means to achieve spiritual liberation. Unfortunately, many today’s Hindus are unfamiliar with this sacred belief. The modern puritanical attitude towards sex, which was imposed on India first by Muslims and later by the British, has left little room for Hindus to practice their ancient traditions in this area.

A woman is not allowed to be approached for sexual purposes during her ritu, a period of sixteen days within her menstrual cycle. If she is sexually involved during this time, she will conceive sons on even nights and daughters on uneven ones.

Moreover, a man should not refuse sex with women who want progeny. This is because he should not break the link between his present life and the life that will follow. The principal Upanishads compare sex to a sacrifice and suggest that he who knows this ties should not refuse sex with any woman who desires progeny.


The ancient Indian texts of Hinduism, Buddhism and Jainism reveal a wide range of moral perspectives on sex. These texts, including the Kama Sutra, feature sexual pleasure as a part of a husband and wife’s duty to please each other. They also suggest that polygamy was common among royalty and other aristocrats, while common people kept monogamous marriages.

The frank depiction of uninhibited sex in the temple sculptures of Khajuraho and other places is another indicator of India’s early acceptance of sexual liberalism. However, when Victorian English values and the influence of Islamic and Indian religions came to power, sexual liberalism receded.

In the context of India’s extended family systems, repressed sexuality has been a factor in what might be called widespread incest, though hard statistics are not available. Sexual relations between brothers and sisters; cousins; uncles and nieces; and aunts and nephews have been quite common in Indian culture, even in modern times.

In recent years, the Indian LGBTQ+ community has been growing in visibility and acceptance. A renaissance of sexual liberalism has sprung up in well-educated urban areas, as more young Indians seek higher education abroad and access the Internet, but discrimination against homosexuals still exists in many parts of India.

There’s no doubt that human sexuality—with all its taboos, rules, and regulations—has been a dominant force in the world’s cultures since prehistoric times. And while we may all have some of the same basic desires, we vary tremendously in how early we start having sex, how open we are about it and how many partners we have.

For example, a new study suggests that some of the modern humans who arrived in Eurasia far earlier than previously thought also had sex with Neanderthals. Researchers found that, buried in the fossil of an ancient Neanderthal, was a small amount of human DNA.

It’s probably safe to say that bestiality has been around for a long time. It’s been shown in rock art, and has been portrayed in paintings as early as the Renaissance period. Until recently, however, it’s been difficult to know how widespread the practice actually was. That is until a young man from Utah lived out many scientists’ dreams. Thad Roberts is a triple-major with degrees in physics, geology and geophysics who wants to be the first person to have sex on Mars. And while he hasn’t had sex on Mars yet, he did have a little bit of fun in the process.
