Sexual arousal
Sexual arousal
Sexual arousal (pronunciation: /ˈsɛkʃuəl əˈraʊzl/) is the physiological response that is often preceded by or in response to sexual desire, a desire to engage in sexual activities.
Etymology
The term "sexual arousal" is derived from the Latin word "sexualis" meaning "relating to sex", and the English word "arousal" which means "to awaken or stimulate".
Definition
Sexual arousal involves changes in bodily functions, the release of neurotransmitters and hormones, and the activation of the nervous system and endocrine system. It can result from a variety of stimuli, including physical stimulation, erotic thoughts, images, or the presence of a desired sexual partner.
Physiological changes
Physiological changes during sexual arousal can include increased heart rate, elevated blood pressure, and changes in genital response such as erection in males and lubrication and swelling in females. These changes are primarily driven by the sympathetic nervous system.
Psychological aspects
Sexual arousal also has psychological components. It can be influenced by a person's emotions, thoughts, and perceptions. The psychological aspects of sexual arousal can include feelings of desire, excitement, and pleasure.
