Tips for razor burn 'down there'?

Katyana
Every time I shave down South I get atrocious razor burn! My husband doesn't care but I really mind the way it looks and it hurts when my underwear rubs up against it! How do you prevent razor burn down there? I've tried exfoliation and different types of hair removal but as the hair grows back the follicles get badly inflamed it's like there's no preventing it.
