How can i make my butt bigger and toned naturally?

Yeah, dont tell me to like myself the way i am. I do. Just not my butt... And techniques and excercises? If you have done this yourself and it worked that would be helpful. I've seen the books that supposedly have secret techniques, but i dont want to spend my money. If youve read those books or found a webpage or have ideas from somewhere else, please share. Thank you(:
