If you look at a diagram of the anatomy of the vagina, it should give you a better perspective on where everything is located. And for your research, the urethra (the pee hole) is located just above the vaginal opening. That's where menstral flow (period blood) comes out, and where the penis is inserted. There is a significant amount of skin between the urethra and the vaginal opening and the inner labia and clitoris.
Try searching on Google for a good female anatomy diagram. Your girlfriends in the future will thank you.
