Shaving...

Jessica
Seeking advice, feedback, suggestions...
So I used to wax because it was a lot easier, but because of the cost I haven't been able to in quite some time. 
So now I've just been shaving. But I keep having the same issues over and over. 
1.  My skin is really pale and even if I shave you can see the hair that has yet to grow in yet through my pores. 😒
2. My hair is naturally really dark (almost black) and extremely thick. So when I do shave it's a work out. It takes me a minimum of 30 minutes to even shave my legs and depending on the razor I use I go through multiple disposables in just one sitting. 
3. My skin is really sensitive and I seem to always get razor burn and or in grown hairs. 
4. And if I try to shave multiple days in a row the razor burn just gets worse and I can't seem to accomplish a smooth shave. 
Anyone else have these issues and can help me?
