Strawberry buttocks🍓🫤

What recommendations do you guys have to get rid of this? I shave part of my buttocks and it gives me the worst razor bumps that look all red and itchy. Even if I don’t shave I sometimes get them. I use cotton panties and sleep without them to let my skin breathe at least. I try to moisturize everyday as well. There are dark spots from old razor bumps and it throws my confidence as well. I’ve thought about using Nair but not so sure how safe it is.
