Clitoromegaly (or macroclitoris) is an abnormal enlargement of the clitoris that is mostly congenital or acquired, though deliberately induced clitoris enlargement.
An enlarged or swollen clitoris is usually caused by normal sexual arousal. Otherwise, a hormone imbalance or medical condition such as PCO.
The clitoris really isn't that confusing. Or it shouldn't be, anyway. Nonetheless, acknowledging the shape, size, or even existence of this.
You probably don't, because nobody seems to talk about this, so I'll just come out and say it: I have a huge clitoral hood. I mean, maybe "huge".
