Sexual arousal

Physiological and psychological changes in preparation for sexual intercourse

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.
