How to make your bum look bigger

I have a small bum, almost flat tbh and I hate it so much. It makes me feel so insecure and I’m always worried boys won’t like me because of it. It’s not fair that I don’t get a nice bum when all these other girls naturally have nice round ones. I’ve tried squats and they don’t really do much for me, so does anyone have tips on how to get a bigger bum? Or at least make it appear bigger
