I think it depends on the sub and Domme. Not all subs respond to CP and it’s easier to discipline or punish them differently. All relationships are different. You need to find a dominant lady that understands your needs and motivations and will use them to train and have you want to submit to her.
honestly, in my experience so far: corporal punishment IS a necessity. not because of something you have done or because you deserve it. it’s a necessity that needs to happen randomly simply because she wants that to happen. it makes sure who is in charge.
