A complication of circumcision where the lack of adequate shaft skin causes hairy pubic and scrotal skin to be drawn onto the erect penile shaft (also called Hirsute Penis). 

During intercourse, this haired skin enters the vagina, causing chafing and irritation for both partners. The skin of the intact penis is smooth and free of hair.
