Sexual arousal, or sexual excitement, is the arousal of sexual desire, during or in anticipation of sexual activity. Things that precipitate human sexual arousal are called erotic stimuli, or colloquially known as turn-ons. There are many potential stimuli, both physical or mental, which can cause a person to become sexually aroused. Sexual arousal usually leads to physiological changes in the aroused person, some of which are pronounced while others are more subtle.
