How to avoid razor burns?????

Ive literally done EVERYTHING to avoid razor burns and i still get them. I switched to mens razors and started using coconut oil before and after and its all good for about a day and then i start burning and itching like CRAZY. I dont want to wax or use cream bc shaving is quick and i don’t mind it but its just the aftermath of it that i cannot handle.

What am i doing wrong?????? Someone please help me out
