Blue Bulbs

The vaginal equivalent of blue balls. When a person with a clitoris and a vagina gets turned on and bulbs of vestibule (also know as clitoral bulbs) become engorged with blood. When the blood does not return to the circulatory system, it can cause discomfort and a tense feeling in the vagina.

Riley: He didn't make you cum last night?
