I sub to my wife (of ten years) when she occasionally feels moved to domme me.

I feel I would like to experience humiliation but neither of us can think how to achieve this. I feel completely at easy with her. Being naked is not a problem. I am comfortable masturbating for her when commanded to do so. What could she do that would create humiliation/embarrassment?

Sadly, she refuses to involve anyone else in our scenes, so having me play the slave in front of other women (or even men) is out, even though I would find that greatly humiliating.

Does anyone out there have any suggestions?
