If you trust her so much why do you need to see proof on a cam or a pic? Hummmm?

Besides once you realize that virtutally anyone can farm your cam sessions and pics off your computers...is it all that safe anymore. At the very least I reccomend no recognizable features or face shots. Common sence should prevail.

I was allways tuaght that a dominant should only have as many submissives as he/or she is actually capable of maintaining "wise" dominion over.

Also, nothing says a dominant has to play favorites, though I have often seen multiple submissive holding dominants do so, but I have seen from personal experience that when a new girl is added to a relationship, especially one in which the primary D/s couple is married, one must take great care to not upset the deliquate balance of the hierarchy.

Obviously if the needs of all the members of a relationship are not being met there will be difficulties.

From the sounds of it your both brand new to this and may wish to slow down a bit before you go adding other submissives to the mix ... or dominants for that matter. (yes some submissives have multiple dominants)

When and if you both decide that adding more partners to the equation is wise or desierable you may wish to keep in mind that things should stay mutually safe, sane and consensual for all parties. That includes all parties knowing and approving of all other parties and or their activity levels.

Just curious but why isn't your wife also a member here?
