razor burned booty

I've been shaving "down there" for awhile but only recently (after becoming sexually active) starting shaving the unfortunately large amount of hair on my butt (cheeks and crack). However, this has resulted in some pretty serious razor burn ALL OVER my butt and it's so visible and embarrassing, it looks like a lot of small pimples/bug bites and I am too embarrassed to be pants-less in front of my bf anymore ): does anyone have tips for how to heal razor burn fast and remove the hair without causing any further damage?
