Calisthenics exercises best for legs and glutes?

hi,
i've been doing calisthenics for maybe a month or two now and have just now started to worry about my butt. i know that sounds really weird and kinda funny but honestly? i do a lot of cardio and a crap ton of strength training exercises, but i don't use weights at all besides my body.
a muscle can't grow unless there's resistance or weight being used as an added force and i'm worried that my butt is going to shrink and not become more perky with all the leg exercises i do. (i do a LOT of lunges and squat/squat jumps)
i'm not really afraid of it shrinking a little, but obviously as i lose more body fat, as i'm also cutting, my butt will shrink along with it.
i'm really on here asking for advice of what i should do, i would really prefer to keep doing calisthenics exclusively as i have no money or access to extra weights or resistance bands :(
what exercises should i do constantly and how many i should do, what i should eat (i only eat steamed chicken and broccoli with occasionally some beans).
it's putting me into a state of anxiety for no reason.
and if it answers any questions, yes my butt is fairly larger than average and my legs are definitely a little more muscular and larger than average as well.
anything would help me with this - thanks guys.
