Nair down there??

Okay. So I've tried shaving and cannot get all the spots. I'm sure u know what I'm talking about. Lol. And I do not have a high pain tolerance to wax. So I guess my question is does waxing actually hurt that bad? Does anyone know a method of shaving that will get it all? And can you put nair down there, not in it just on it?? Please help. Its so aggrivating.
