People need to think of time-frames before they simplistically equate ”non-consent” in some form with “abuse”. My wife consents to DD in her long-term, wisest, mind. Since DD sometimes involves me dominating her, forcing her to behave differently than she wishes at the time and/or punishing her when she is utterly opposed to the idea, DD is not always fully consensual in the short-term. Overall, despite some short-term regrets and struggles, in the long-term she really values and appreciates my dominance and disciplinary care.
DD which the recipient could wriggle out of at any time would be a sham.
Likewise most people who, in the fullest sense, “like” being spanked wouldn't be very interested in it if at the time of the spanking they were not suffering pain and regret or if their pleas to stop it were heeded.
Likewise a roller-coaster, which is long-term consensual but short-term non-consensual. Good roller coasters and good DD are very safe and have all sorts of unique benefits which arise directly from their forceful, safe, exciting and/or beneficial short-term domination.
