Well I can assure you you're not the only one here who's scared. I mean: being dominant I'm not the one completely giving over control to another person who might do god knows what and it still scares the shit out of me!

I'm not trying to make you any more nervous than you are already though, my point is just that I'm pretty sure that I guess I'd be more nervous for a newbie like you and myself if we were NOT scared. As people have already pointed out there are good reasons to be careful when you're a submissive and I if I was one I'm pretty sure I'd find any new dom who was not nervous about the kind of responsibility he or she'd be taking quite terrifying!

In my opinion courage is not about not being scared but about facing the things you're really scared of . Bungee-jumping or skydiving is not nearly as courageous if you're not afraid of heights as it if you are, subbing as well is so much more courageous if one is not comfortable loosing control.

So I guess what I'm saying is that instead of worrying about your (quite rational, at least in part) fear about submitting to someone else, you should focus on the fact that what you're doing is quite courageous, especially for you.

That said I agree that you should listen to all the good advice from everyone here about not throwing yourself on your knees for just anybody.
