Sexology

Sex, more formally known as sexual intercourse, coitus, or copulation, is an intimate social activity typically involving the insertion of the erect male penis inside the female vagina and followed by thrusting motions for erotic pleasure, biological reproduction, or both. This specific type of sex is also known as vaginal intercourse. However, other forms of penetrative sexual intercourse also exist, including anal sex, oral sex, fingering and penetration by use of a dildo, and vibrators. The desire for these activities is grounded in natural human instinct and they involve physical intimacy between two or more people, usually enacted by humans solely for physical-emotional pleasure, sometimes contributing to human bonding.

Sexology is the scientific study of human sexuality, including human sexual interests, behaviors, and functions. The term sexology does not generally refer to the non-scientific study of sexuality, such as social criticism.

A sex position is a positioning of the bodies that people use to engage in sexual intercourse or other sexual activities. Sexual acts are generally described by the positions the participants adopt in order to perform those acts. Though sexual intercourse generally involves penetration of the body of one person by another, sex positions commonly involve non-penetrative sexual activities.

A paraphilia is an uncommon, intense, and persistent sexual arousal or attraction to anything not sexual by nature, though substitutions of preferential for intense are favored for specific designations. It has also been defined as a sexual interest in anything other than a legally consenting human partner. Paraphilias are contrasted with normophilic ("normal") sexual interests, although the definition of what makes a sexual interest normal or atypical remains controversial.

Orgone ( ) is a pseudoscientific concept variously described as an esoteric energy or hypothetical universal life force. Originally proposed in the 1930s by Wilhelm Reich, and developed by Reich's student Charles Kelley after Reich's death in 1957, orgone was conceived as the anti-entropic principle of the universe, a creative substratum in all of nature comparable to Mesmer's animal magnetism (1779), to the Odic force (1845) of Carl Reichenbach and to Henri Bergson's élan vital (1907). Orgone was seen as a massless, omnipresent substance, similar to luminiferous aether, but more closely assoc

Sexophobia is the fear of sexual organs or sexual activities and, in a larger sense, the fear of sexuality.

Sociosexuality, sometimes called sociosexual orientation, is the individual difference in the willingness to engage in sexual activity outside of a committed relationship. Individuals who are more restricted sociosexually are less willing to engage in casual sex; they prefer greater love, commitment and emotional closeness before having sex with romantic partners. Individuals who are more unrestricted sociosexually are more willing to have casual sex and are more comfortable engaging in sex without love, commitment or closeness.

In psychoanalytic theory, aphanisis (; from the Greek ἀφάνισις aphanisis, "disappearance") is the disappearance of sexual desire. The etymology of the term refers to it as the absence of brilliance in the astronomical sense such as the fading or the disappearance of a star. Psychoanalyst Jacques Lacan used the term in reference to the fading or disappearance of the subject.
