Chastity and orgasm denial discussion

Hello I’ve dabbled in the sub/dom scene for a while, including some chastity play. I’m always keen to see how you can alter a submissive’s posture. It’s delightful to watch someone humiliated yet forced into upright, proud positions. I also have a passion for corsets and historical pieces, so these interests blend well. I’ve discovered that certain shoulder braces, corsets, and posture collars can shift a sub from rounded shoulders to a model of Victorian elegance. Has anyone else attempted serious posture training? Historically, posture training was standard practice for young ladies to improve their silhouette and chances of finding a husband. Annie
