Really need some female advice...

Okay I see a lot of women who are flat down there... I don't know how to explain this... where the pubic hair grows (I'm not sure what this triangular area is called). it's like a mound. I see that most women when they lay down, it's flat and looks nice, but when I lay down, that area is like a mound. It embarrasses and I'm not sure if it's even something to be embarrassed about. I hope that someone will understand what I'm saying and tell me if you are flat or have a mound down there... tyia
