Chastity and orgasm denial discussion

Greetings everyone, Has anyone captured (somewhat humiliating) images of themselves wearing their chastity device, or posed for their partner while they were taking photos? And then had those pictures “stored away” by that person (perhaps in a safe deposit box at the bank)… to be used later to give them even more control over you? And to assist in keeping you committed to chastity? I would imagine that simply knowing they possess these images of you, “secured” so there is no denying you wear the device, could have a powerful (submissive) “psychological impact” on the wearer….? Do any Key Holders or Mistresses utilize “photos” of their subs as an aid to maintain chastity? I suppose a reasonable next step (with plenty of trust!!) would be to provide various other nude, embarrassing, and humiliating pictures/videos for the Key Holder… and sign a model release or contract granting them publishing rights and/or ownership of these images or videos. Sooo if “someone” decided they wanted to exit chastity, it could become VERY awkward for them if their Key Holder determined that the cost for “freedom” was having those photos/videos published across several websites! Oh dear… j
