Confession seems “easy” if you keep it up and stay away from mortal sin, yes.
When you fall so hard into temptation that you can’t get out of it for months, thats when it gets tricky. Just getting yourself to the confessional is a feat in itself, but turning away from the temptation of sin is even harder. So considering you have to be in a mindset not sin again and actual repentance, I would say that the “difficulty” of confession is relative to where you are in life.
