Clitoral erection is a physiological phenomenon where the clitoris becomes enlarged and firm. Clitoral erection is the result of a complex interaction of psychological, neural, vascular and endocrine factors, and is usually, though not exclusively, associated with sexual arousal.

[edit] Physiology

The internal anatomy of the human vulva, with the clitoral hood and labia minora indicated as lines.

Clitoral erection occurs when the corpora cavernosa, two expandable erectile structures, become engorged with venous blood. This may result from any of various physiological stimuli, including sexual stimulation and sexual arousal. The extrusion of the glans clitoridis and thinning of the skin enhances sensitivity to physical contact. After a female has orgasmed, the erection usually ends, but this may take time.

[edit] Shape and size

An erect clitoris can take on a number of different shapes and angles, ranging from small and embedded, to large and protruding. Generally, the size of an erect clitoris is fixed throughout post-pubescent life.

[edit] Priapism

A clitoral erection that does not subside is a form of priapism called clitoral priapism. It is a painful condition.
