vagina pics?

I love sending pictures to my long distance bf usually of my boobs or in my undies. He always pushes for vagina pics though, I just feel like I can't get a good angle and even if I get what I think is a good angle, I just don't like the idea of my vagina so out in the open. Do guys really find this hot? Can you ladies give me any tips on how to make these pictures seem somewhat attractive??
