Do females have three openings in their pelvic region?

Yes. The vagina (vaginal orifice), anus, and urethra (for peeing). See the Related Link below for a 3D diagram of the vagina (from an underside view, looking up). The second Related Link will show you a real-life picture of a woman's vagina (from an underside view, looking up). If you are under 13, please ask your parents for permission to view this photo. Note to other Supervisors: this is not porn. It is a medical photo from a nurse practioner's website.
