I told my plastic surgeon that I didn't want a butt with a high shelf, but I did want projection. I just wanted it to look like a more gradual slope. He responded by saying, "Oh, you want the bubble shape", but I am not sure that this it the shape I want because we didn't discuss options for shapes and I am not sure that "bubble" describes what I want. Can you please tell me (and show with photos) the different options for shapes?
