BOOTY WORKOUT!

I'm sooo insecure with my butt I literally have a flat ass I think it's so unattractive and when I wear leggings they're so bad I always revert to wear skirts because of this.

Is it possible to have a big, well at least plump butt without going to the gym just doing it at home whatsoever?

What should I do to start? I've been doing squats for 2 months but I don't really see any difference yet. Is squats enough?
