See, to me this is self-contradictory. I do not think that doms are nessecarily more confident, because if they were, they would dare to ask if they needed info. It is the responsible thing to do when to are you the one with the responsiblity - and we all need info.
And a lot of subs are confident. Contrary to what is said here often, I do not think subs are a class of fragile little flowers ;-)
And there are posts here and there that points towards this being a problem for a number of doms.
ehm - doms? ;-)who doesn't like the occasional chat with like-minded people?
