Sexual arousal (also known as sexual excitement) describes the physiological and psychological responses in preparation for sexual intercourse or when exposed to sexual stimuli. A number of physiological responses occur in the body and mind as preparation for sexual intercourse, and continue during intercourse. Male arousal leads to erection, cremaster reflex and pre-ejaculate; in female arousal, the body's response is engorged sexual tissues (such as nipples, clitoris, and vaginal walls), changes to the cervix, and vaginal lubrication.

Sexual arousal has several stages and may not lead to any actual sexual activity after mental stimuli have brought about accompanying physiological changes. Physical stimuli, such as touch, and the internal fluctuation of hormones can influence sexual arousal. Given sufficient and appropriate sexual stimulation in the right context, sexual arousal intensifies to a high level and can precipitate an orgasm as part of the climax. Mental or physical stimulation may also be pursued for their own sake, even in the absence of orgasm.
