Do you ever find yourself avoiding to add sub tasks because you simply don't want to do that thing you've been putting off?

No, because, (and this is the trick for me) adding tasks and subtasks and planning is a completely separate activity and headspace. When I am doing that, I am in planning mode and I don't imagine how much it will suck to do a task. Just plan.

Then when I do, I just do.

This planning and review phase you describe is the first step in a GTD workflow.
