I love the pictures and analysis Thanks! So the female vs male difference on the shots of the urogenital opening.. how would you describe the difference so others can see what you are seeing?

TO me the front hole is consistent male/female, the back hole is round and small on the male and on the female seems to have an upside down keyhole shape with the horizontal part near the front and the arch going towards the rear.






Is there a better way to describe the difference? Or another difference?
