Razor burn? Bumps?


I was curious if there was some secret that all women know except me when it comes to shaving "down there"? I read you can get a really close clean shave when using coconut oil, I tried it and it does give me a close clean shave but I get razor burn and that's definitely something I'm trying to avoid! I heard if you use deodorant after shaving it helps A LOT. I'm just curious if you guys have a different method and if it works better. I'm open to whatever suggestions you guys might have!

Thanks in advance
