I am reading a book called the Atlas of Anatomy and it reads,
"The clitoris is actually similar in structure to the penis, even to the extent of having a hood of labia equivalent to the foreskin and a small connecting band of tissue called the frenulum.
It is primarily an organ of sexual excitement. It is extreamely sensitive and when stimulated its spongy tissue fills with blood and becomes erect. Friction on the erect clitoris will usually lead to orgasm"
It must be great to be born female, you get to have a penis and a vagina at the same time. 2 for one deal.
