I do butt workouts all the time but still don't have a big butt? Any tips?

I workout almost every day, and I do butt workouts 3-4 times a week. My butt is still flat and my friends sometimes tease me about having "no ass."
Is it just genetics of can I do anything? I want a really big, round bum.
Also, is it bad right now? Don't be too harsh lol
