Shaving?!?

Kim
Ok so I shave legs,pits, and vagina! I nvr get razor burn any where other then my vagina I have absolutely tried every thing  to stop it!! I have heared that good lotion can prevent it. Now my question is is it ok to put pure coco butter lotion on that area. The burns and bumps are only at the top it's not on lips or any where else. So will it be okay to but a little bit of coco butter on top of that area?if not any suggestions that could help be out?!?
