Erectile tissue is tissue in the body with numerous vascular spaces, or cavernous tissue, that may become engorged with blood. [ 1 ] [ 2 ] However, tissue that is devoid of or otherwise lacking erectile tissue (such as the labia minora , vestibule , vagina and urethra ) may also be described as engorging with blood, often with regard to sexual ...
The human penis is made up of three columns of erectile tissue: two corpora cavernosa lie next to each other (separated by a fibrous septum) on the dorsal side and one corpus spongiosum lies between them on the ventral side. [7] These columns are surrounded by a fibrous layer of connective tissue called the tunica albuginea.
The perineal sponge is composed of erectile tissue; during arousal, it becomes swollen with blood compressing the outer third of the vagina along with the vestibular bulbs and urethral sponge thereby tightening the vagina and increasing stimulation for the vagina and a penis, if involved. [1]
Research indicates that the vestibular bulbs are more closely related to the clitoris than to the vestibule because of the similarity of the trabecular and erectile tissue within the clitoris and bulbs, and the absence of trabecular tissue in other genital organs, with the erectile tissue's trabecular nature allowing engorgement and expansion during sexual arousal. [1]
During sexual arousal, arterial blood flow to the clitoris is increased, and within the clitoris, the arteries further branch to supply the erectile tissues. The trabecular smooth muscles of the erectile tissue relax increasing blood flow to fill the vascular spaces, and expanding the erectile tissues until they are fully engorged with blood. [ 7 ]

From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
The urethral sponge is composed of erectile tissue; during arousal, it becomes swollen with blood, compressing the urethra, helping, along with the pubococcygeus muscle, to prevent urination during sexual activity. [citation needed]
