Problem analysis: When a woman lies on her back on the bed with her legs spread out, under the pubic mound (where the pubic hair is located) and the big and small labia are separated, she will see two holes (holes) under the clitoris of the vestibule (where the two small labia meet-that is the sensitive area of women). The smaller upper end is the urethral orifice; The larger one at the lower end is the vaginal opening.
Thank you for paying attention to the network, and I wish you health!
