Speaking from total ignorance here since humiliation isn't my kink, but, since you performed this task in front of the vanilla public, perhaps afterwards your mind viewed yourself and the task from the perspective of the vanilla public. (Let's face it, vanilla grandma who saw would purse her lips and say what a slut, how appalling). Once you spoke to your dom, your mind was able to view yourself and the task from his bdsm perspective. (Excellent sub - Very hot and freeing.) I bet you could have spoken to anyone here at the forum, and gotten the same shift in perspective. So until you are comfortable enough in your role as a sub that your mind isn't torn, you probably just need to seek reassurance here if your dom isn't available. You know you can always find love and support here. Don't wait to seek it.
