Am I doing this wrong?

I’m 16 and I’ve tried multiple times (3 times now) to shave my pubic hair but every single time it starts growing back it becomes unbearably painful and extremely itchy.

I’ve tried so many ways to prevent this from happening. From shaving with warm water and shaving cream to baby oil, coconut oil, hair conditioner, putting on petroleum jelly afterwards or aftershave or aloe Vera gel but nothing works.

Even when I try to shave it doesnt look like I’ve actually shaved it. My pubic hair is so course and dark that even when I shave it you can still see basically all of it since my skin down there is relatively pale.

At the moment I have given up on shaving there completely but it sucks during the summer time and I want to be able to shave down there without having to go through the hassle of the regrowing stage!!! (Most of the time when I shave when my hair grows back it starts to itch. Am I just shaving wrong?)
