horny

Horny is a colloquial English adjective meaning sexually aroused. It can describe a person who is experiencing sexual desire or arousal; the term is gender-neutral in modern usage, though it is informal and may be considered vulgar in certain contexts. The related noun “horniness” refers to sexual arousal.

Etymology: The precise origin is uncertain, but the sense is thought to derive from metaphorical use of “horn” to signify strong energy or readiness, with the sexual sense developing in the 19th or early 20th century. Historically the word has carried broader connotations of agitation or eagerness beyond sexuality.

Physiology and psychology: Sexual arousal involves the autonomic nervous system and hormonal influences. In people with penises, arousal commonly leads to erection; in those with vulvas, vaginal lubrication and clitoral or labial engorgement may occur. Other signs can include increased heart rate, breathing, and skin flushing. Psychological factors such as fantasies, attraction, mood, and context can influence arousal, and the experience varies greatly between individuals and situations. Arousal can occur intentionally or spontaneously and does not necessarily indicate readiness for sexual activity or consent.

Social and cultural context: Because horny is informal, it is not appropriate in many formal or professional settings and may be offensive to some. Language around sexuality varies across cultures and ages; people may choose to use more clinical or neutral terms in certain contexts.
