The only moment you write comments is when you are doing something extremely weird for a specific reason that will not be immediately obvious and you want to warn the person doing a refactor in the future. In any other case, writing self documenting code is the way. If you are unable to do that, then your code needs to be rewrtitten.
Self documenting code is a myth as what's self documenting to one person is not to the next. Code comments and process/workflow documentation is needed for a healthy codebase.
I have given well documented code to plenty of juniors, it comes with being a senior dev / techlead. And it was perfectly understood. Maybe you simply don't write self documenting code.
