PW: We use it, but nowhere near as heavily as people have implied their families are. It was started entirely at her request. It has worked out really well. We're both strong-willed when we really stand our ground. We love each other, but when we argue we get really shouty. We got written up by the apartment management once because the neighbors could hear us! When she asked to go to lifestyle-dominance, she wanted to use caning to settle the arguments. It was effective and it turns out to be less hurtful than words. Also I like that I can force her to be on time for stuff, evil laugh, because tardiness is a big pet peeve of mine! This lets her follow her natural submissiveness and just do what she's told, so I barely ever use the cane anymore.
Corner time was also 100 percent her idea and I'm 100 percent sure she got it from here. She only asked about it right around the time quarantine began. It's kind of worked out because our problem is our tempers get really heated. Putting her in the corner for a while shuts her up and I tend to just stay away, and by the time it's over we've both cooled down.
It took me some time to get used to, because it feels like I'm doing something wrong, but it makes her happy and settled a bunch of problems. So I roll with it.
