How do I end razor burn around my female area?

I have a clean razor, a four blade, venus. It's a GREAT razor, doesn't leave razor burn anywhere but around my vagina. How can I stop this?|||Just use a different method. I use a hair removal cream such as Veet with great success. As part of your daily routine your area will always be neat and smooth.|||dont shave it.|||I know this sounds really weird, but put deoderant on it, it actually works and prevents the annoying razor burn
