x. Vasocongestion

In the woman there is increased blood flow to the labia majora, labia minora and clitoris, and there is vaginal lubrication (transudation). The entrance to the vagina narrows, but the inner two-thirds of the vagina dilates. As the woman becomes more sexually aroused, vasocongestion causes the clitoris to enlarge, in terms of both its diameter and the length of the shaft) and the glans and shaft withdraw under the clitoral hood (next to the anterior part of the symphysis). The same nerve pathways and neurotransmitters are probably involved in sexual arousal in men as well as women.
