Word of the Day

aka vascular congestion of the sex organs (i.e. getting a boner for men, getting aroused for women)

Anatomy lesson: The penis is made of cavernous tissue that fills with blood upon arousal. This then extends the penile tissue and stands it erect against the pelvis. Women's genitals also engorge with blood upon arousal, though not quite as dramatically!
