Sexual attraction

Sexual attraction is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sexual attraction rather than just read about it. In short: 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.

Key takeaways

  • Sexual attraction belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sexual attraction to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sexual attraction from memory before moving on to harder problems.

Reference excerpt

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, movements, voice, among other things. The attraction may be enhanced by a person's body odor, sex pheromones, adornments, clothing, perfume or hair 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. Though attempts have been made to devise objective criteria of sexual attractiveness and measure it as one of several bodily forms of capital asset (e.g. erotic capital), a person's sexual attractiveness is to a large extent a subjective measure dependent on another person's interest, perception, and sexual orientation. For example, a gay or lesbian person would typically find a person of the same sex to be more attractive than one of the other sex. A bisexual person would find either sex to be attractive. Asexuality refers to those who do not experience sexual attraction for either sex, though they may have romantic attraction or a non-directed libido. Interpersonal attraction includes factors such as physical or psychological similarity, familiarity or possessing a preponderance of common or familiar features, similarity, complementarity, reciprocal liking, and reinforcement. The ability of a person's physical and other qualities to create a sexual interest in others is the basis of their use in advertising, film, and other visual media, as well as in modeling and other occupations. In evolutionary terms, the ovulatory shift hypothesis posits that female humans exhibit different sexual behaviours and desires at points in their menstrual cycle, as a means to ensure that they attract a high quality mate to copulate with during their most fertile time. Hormone levels throughout the menstrual cycle affect a woman's overt behaviours, influencing the way a woman presents herself to others during stages of her menstrual cycle, in an attempt to attract high quality mates the closer the woman is to ovulation.

Social and biological factors

Human sexuality has many aspects. In biology, sexuality describes the reproductive mechanism and the basic biological drive that exists in all sexually reproducing species and can encompass sexual intercourse and sexual contact in all its forms. There are also emotional and physical aspects of sexuality. These relate to the bond between individuals, which may be expressed through profound feelings or emotions. Sociologically, it can cover the cultural, political, and legal aspects; philosophically, it can span the moral, ethical, theological, spiritual, and religious aspects. Which aspects of a person's sexuality attract another is influenced by cultural factors; it has varied over time, as well as personal factors. Influencing factors may be determined more locally among sub-cultures, across sexual fields, or simply by the preferences of the individual. These preferences come about as a result of a complex variety of genetic, psychological, and cultural factors. A person's physical appearance has a critical impact on their sexual attractiveness. This involves the impact one's appearance has on the senses, especially in the beginning of a relationship, among them:

Visual perception (the symmetry of the face, physical attractiveness, health, and how they act or move, for example, while dancing); Audition (how the other's voice and movements sound); Olfaction (how the other smells, naturally or artificially; the wrong smell may be repellent); Somatosensory system (for example touch and temperature). As with other animals, pheromones may have an impact, though less significantly in the case of humans. Theoretically, the "wrong" pheromone may cause someone to be disliked, even when they would otherwise appear attractive. The importance of pheromones in human relationships is probably limited and is widely disputed, although it appears to have some scientific basis. Some people exhibit high levels of sexual fetishism and are sexually stimulated by other stimuli not normally associated with sexual arousal. The degree to which such fetishism exists or has existed in different cultures is controversial. Pheromones have been determined to play a role in sexual attraction between people. They influence gonadal hormone secretion, for example, follicle maturation in the ovaries in females and testosterone and sperm production in males.

Worked examples

Example 1 — a first encounter with Sexual attraction

Start with the simplest possible case. Write down what Sexual attraction claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sexual attraction before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sexual attraction ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sexual attraction

In research
Sexual attraction appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sexual attraction in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sexual attraction is common in secondary-school and first-year university syllabi. It links to neighbouring topics Evolutionary psychology, Physical attractiveness, Sexual attraction, so understanding it makes those chapters shorter.
In everyday life
Look for Sexual attraction outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Sexual attraction in simple terms?

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.

Why does Sexual attraction matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Sexual attraction?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
