I'm disgustingly new to all of this, and yet I think I may have messed it up already.

Is it possible to mess up on a first attempt at being a Domme so badly that your sub decides they'd rather be vanilla again than be your pet? Is it normal for a Domme to feel heartbroken/like a complete failure when/if her first subbie leaves or threatens to leave or says their interest is slipping? Do Dom/mes even have self-confidence issues?

I realize this is one of those things that 'you just have to deal with cause life's like that'; I just really need to know if it's not uncommon to feel like such a fuckup over something like this.
