Definition

Sexual arousal is the process and state of an animal being ready for sexual activity. Unlike most other animals, human beings of both sexes are potentially capable of sexual arousal throughout the year, therefore, there is no human mating season.

Signs of Sexual Arousal in Both Genders

Human males and females share similar signs of potential sexual arousal.

• Increase in breathing rate.
• Increase in blood pressure
• Increase in muscle tone (myotonia)
• Increase in heart rate (tachycardia)
• Vasocongestion of the skin ('sex flush')
• Slight or extreme dilation of the pupils (though especially so with females)
• Erection of the nipples (especially upon direct stimulation)
• Release of pheromones (our natural scent)
