Erectile tissue is tissue in the body with numerous vascular spaces that may become engorged with blood. However, tissue that is devoid of or otherwise lacking erectile tissue (such as the labia minora, the vestibule/vagina and the urethra) may also be described as engorging with blood, often with regard to sexual arousal.
