LOL! That is hilarious!! I thought it was from his bondage, not his ego. Awesome.
As for actual bondage, I do mine with the sub lying prone because I know full well and good where my strengths lie. I'm 1) too impatient to leave a sub hanging without wanting to take them down immediately where I can play with them safely again and 2) NOT a shibari master... just a bondage enthusiast. Very different things.
