Nearly every online D/s player has faced this major issue of trust. To send or not to send intimate pictures, or do intimate video chatting is the issue.
This is not a small concern, as the internet is overloaded with images of nude or nearly nude women who had no idea they would be spread across a public domain along with thousands and thousands of tits, pussies and asses of unknowing or embarrassed wives, lovers, subbies .
So it is no wonder so many subs refuse or balk or have nightmares over sending intimate images.... Sending or posting your nude body takes even more trust than permitting completely restraining bondage. That at least can be managed by having proof documents of your partner, like a driver's license, phone number, even a passport photo to insure you know who is tying you up in a scene.
But sending requested or required intimate pictures of your body? Almost impossible to control what 'he' might do with them. So a massive dose of trust is necessary before hitting send.
Yes, the Cage is awash in unscrupulous sharks and packs of hyenas hoping to score nude pics from naive newbie subs signing in for the first time. Many a newbie has responded to their demands before realizing they shouldn't have too quickly sent nudes.
So what can be done ?
I'm no lawyer, but I suppose some form of non-disclosure agreement might be created before sending such images. Cumbersome.
Closer to home here, perhaps the requesting Dom could be (respectfully of course) put on notice that the Cage staff would be notified of any violation of trust. Maybe an on going forum topic could be created to address this issue and any potential solutions. Even so, sometimes months or years go by before the offending images wind up in the public domain.
I'm just going to post this as an ongoing real issue, particularly for those doing online D/s. Of course those doing in person are also vulnerable. Pretty hard to prevent revealing pictures being snapped when you are bound tight and maybe blindfolded.
At its heart, this is entirely a trust issue. Without total trust in the partner asking (or demanding!) such pictures, just feel that big red flag and make it a hard limit unless or until until that necessary trust is created.
Still, having said all that, can't your subbie send your heart racing and your cock stiffening, even half way around the world, by sharing the perfection of her body? She's simply magical ! Like most other visual Doms, I cherish every such image ever gifted me; none ever has, or ever will escape my safekeeping. And that is as it should everywhere be.
