Sadly it seems that there are a lot of "people" who think that by saying they are a dom makes them a dom. This is true on line and in the real world as well.
In other words, there are a lot of butt hols out there.

Just because someone says they are a dom does not make it so. You were quite right to walk away. "Doms" like this are in reality little boys playing with things they will never understand.

They are the ones who should be feeling bad, not you.
