Eroticism is a quality that causes sexual feelings, as well as a philosophical contemplation concerning the aesthetics of sexual desire, sensuality, and romantic love. That quality may be found in any form of artwork, including painting, sculpture, photography, drama, film, music, or literature. It may also be found in advertising. The term may also refer to a state of sexual arousal or anticipation of such – an insistent sexual impulse, desire, or pattern of thoughts.
Sexual themes are frequently used in science fiction or related genres. Such elements may include depictions of realistic sexual interactions in a science fictional setting, a protagonist with an alternative sexuality, a sexual encounter between a human and a fictional extraterrestrial, or exploration of the varieties of sexual experience that deviate from the conventional.
Sexual attraction is attraction on the basis of sexual desire or the quality of arousing such interest. Sexual attractiveness or sex appeal is an individual's ability to attract other people sexually, and is a factor in sexual selection or mate choice. The attraction can be to the physical or other qualities or traits of a person, or to such qualities in the context where they appear. The attraction may be to a person's aesthetics or movements or to their voice or smell, among other things. The attraction may be enhanced by a person's adornments, clothing, perfume or style. It can be influenced by individual genetic, psychological, or cultural factors, or to other, more amorphous qualities. Sexual attraction is also a response to another person that depends on a combination of the person possessing the traits and on the criteria of the person who is attracted.
The Descent of Man, and Selection in Relation to Sex is a book by English naturalist Charles Darwin, first published in 1871, which applies evolutionary theory to human evolution, and details his theory of sexual selection, a form of biological adaptation distinct from, yet interconnected with, natural selection. The book discusses many related issues, including evolutionary psychology, evolutionary ethics, evolutionary musicology, differences between human races, differences between sexes, the dominant role of women in mate choice, and the relevance of the evolutionary theory to society.
Concealed ovulation or hidden œstrus in a species is the lack of any perceptible change in an adult female when she is fertile and near ovulation. Some examples of perceptible changes are swelling and redness of the genitalia in baboons and bonobos, and pheromone release in the feline family. In contrast, the females of humans and a few other species that undergo hidden estrus have few external signs of fecundity, making it difficult for a mate to consciously deduce, by means of external signs only, whether or not a female is near ovulation.
Sociobiological theories of rape explore how evolutionary adaptation influences the psychology of rapists. Such theories are highly controversial, as traditional theories typically do not consider rape a behavioral adaptation. Some object to such theories on ethical, religious, political, or scientific grounds. Others argue correct knowledge of rape causes is necessary for effective preventive measures.
Physical attractiveness is the degree to which a person's physical features are considered aesthetically pleasing or beautiful. The term often implies sexual attractiveness or desirability, but can also be distinct from either. There are many factors which influence one person's attraction to another, with physical aspects being one of them. Physical attraction itself includes universal perceptions common to all human cultures such as facial symmetry, sociocultural dependent attributes and personal preferences unique to a particular individual.
Why Is Sex Fun? The Evolution of Human Sexuality is a 1997 book about the evolution of human sexuality by the biologist Jared Diamond.
Comprehensive sex education (CSE) is a sex education instruction method based on-curriculum that aims to give students the knowledge, attitudes, skills, and values to make appropriate and healthy choices in their sexual lives. The intention is that this understanding will prevent students from contracting sexually transmitted infections, such as HIV and HPV. CSE is also designed with the intention of reducing unplanned and unwanted pregnancies, as well as lowering rates of domestic and sexual violence, thus contributing to a healthier society, both physically and mentally.
Black Sexual Politics: African Americans, Gender and the New Racism by Patricia Hill Collins is a work of critical theory that discusses the way that race, class and gender intersect to affect the lives of African American men and women in many different ways, but with similar results. The book explores the way that new forms of racism can work to oppress black people, while filling them with messages of liberation.
Human sexuality is the way people experience and express themselves sexually. This involves biological, erotic, physical, emotional, social, or spiritual feelings and behaviors. Because it is a broad term, which has varied with historical contexts over time, it lacks a precise definition. The biological and physical aspects of sexuality largely concern the human reproductive functions, including the human sexual response cycle.
A Natural History of Rape: Biological Bases of Sexual Coercion is a 2000 book by the biologist Randy Thornhill and the anthropologist Craig T. Palmer, in which the authors argue that evolutionary psychology can account for rape among human beings, maintain that rape is either a behavioral adaptation or a byproduct of adaptive traits such as sexual desire and aggressiveness, and make proposals for preventing rape. They also criticize the assumption that there is a connection between what is naturally selected and what is morally right or wrong, which they refer to as the "naturalistic fallacy", and the idea, popularized by the feminist author Susan Brownmiller in Against Our Will (1975), that rape is an expression of male domination and is not sexually motivated.
Survival of the Sickest: The Surprising Connections Between Disease and Longevity is a 2007 New York Times Bestselling science book by Sharon Moalem, an evolutionary biologist and neurogeneticist, and Jonathan Prince, senior advisor and speechwriter for the Clinton administration. It was originally titled, Survival of the Sickest: A Medical Maverick Discovers Why We Need Disease.
Sex at Dawn: The Prehistoric Origins of Modern Sexuality is a 2010 book about the evolution of human mating systems by Christopher Ryan and Cacilda Jethá. In opposition to what the authors see as the "standard narrative" of human sexual evolution, they contend that having multiple sexual partners was common and accepted in the environment of evolutionary adaptedness. The authors contend that mobile, self-contained groups of hunter-gatherers were the norm for humans before agriculture led to high population density. Before agriculture, according to the authors, sex was relatively promiscuous and paternity was not a concern. This dynamic is similar to the mating system of bonobos. According to the book, sexual interactions strengthened the bond of trust in the groups. Far from causing jealousy, social equilibrium and reciprocal obligation were strengthened by playful sexual interactions.
Odour is sensory stimulation of the olfactory membrane of the nose by a group of molecules. Certain body odours are connected to human sexual attraction. Humans can make use of body odour subconsciously to identify whether a potential mate will pass on favourable traits to their offspring. Body odour may provide significant cues about the genetic quality, health and reproductive success of a potential mate. Body odour affects sexual attraction in a number of ways including through human biology, the menstrual cycle and fluctuating asymmetry. The olfactory membrane plays a role in smelling and subconsciously assessing another human's pheromones. It also affects the sexual attraction of insects and mammals. The major histocompatibility complex genes are important for the immune system, and appear to play a role in sexual attraction via body odour. Studies have shown that body odor is strongly connected with attraction in heterosexual females. The women in the study ranked body odor as more important for attraction than “looks”. Humans may not simply depend on visual and verbal senses to be attracted to a possible partner/mate.
Sexual suggestiveness is visual, verbal, written or behavioral material or action with sexual undertones implying sexual intent in order to provoke sexual arousal.
The Evolution of Human Sexuality is a 1979 book about human sexuality by the anthropologist Donald Symons, in which the author discusses topics such as human sexual anatomy, ovulation, orgasm, homosexuality, sexual promiscuity, and rape, attempting to show how evolutionary concepts can be applied to humans. Symons argues that the female orgasm is not an adaptive trait and that women have the capacity for it only because orgasm is adaptive for men, and that differences between the sexual behavior of male and female homosexuals help to show underlying differences between male and female sexuality. In his view, homosexual men tend to be sexually promiscuous because of the tendency of men in general to desire sex with a large number of partners, a tendency that in heterosexual men is usually restrained by women's typical lack of interest in promiscuous sex. Symons also argues that rape can be explained in evolutionary terms and feminist claims that it is not sexually motivated are incorrect.

Sharon Moalem is a Canadian-American physician, scientist, and bestselling author. Dr. Moalem is an expert in the fields of rare diseases, sex differentiation, neurogenetics, biotechnology and has been described as a polymath. He is the author of the New York Times bestselling book Survival of the Sickest, as well as How Sex Works, Inheritance and The Better Half. His clinical genetics research led to the discovery of three rare genetic syndromes, hypotrichosis-lymphedema-telangiectasia-renal defect syndrome, a form of SRY-negative XX male sex reversal as well as a nephronopthisis associated ciliopathy. His research led to the discovery of a new class of antibiotics that specifically target superbug microorganisms such as Methicillin-resistant Staphylococcus aureus (MRSA). Moalem was the first to propose that the progressive neurodegeneration associated with dementia and Alzheimer's disease might be caused or exacerbated by an excessive amount of the metal iron in the brain. Moalem has cofounded two biotechnology companies and has been awarded 25 patents for his inventions in biotechnology and human health.
The ovulatory shift hypothesis is the scientific hypothesis that women experience evolutionarily adaptive changes in subconscious thoughts and behaviors related to mating during different parts of the ovulatory cycle. In simple terms, it suggests that what women want, in terms of men, changes throughout the menstrual cycle. Some studies have demonstrated evidence in support of the ovulatory shift hypothesis while some reviews have failed to show significant effects for some predictions of the theory. Two meta-analyses published in 2014 reached opposing conclusions on whether the existing evidence was robust enough to support the prediction that women's mate preferences change across the cycle. Some researchers who found an increased preference for masculine traits near ovulation within each cycle also observed variation between cycles―in all cases, attraction towards "high testosterone" men was correlated with salivary estradiol.
