Female Pelvis Showing Erect Clitoris
As a woman becomes sexually excited, her sex organs prepare for intercourse through changes in the circulatory and nervous systems. The pulse quickens, arteries dilate and blood engorges the erectile tissue of the clitoris. The role of the nervous system in sexual arousal is both conscious and unconscious. Although much of arousal begins in the brain and is communicated to the genital area, the biological conversation is two-way; sexual desire fuels genital arousal and genital arousal fuels desire.
