Hi Paul, it's not traditional on this site for us to give helpful advise to newbies who haven't yet made useful contributions (i.e. done reviews).
But as you seem genuine, I recommend Stormy London:
External Link/Members Only(I've not seen her yet. Normally I like to be the dominating one, & pretty much all the women I've been with, civvy or WGs, seem to prefer to be at least mildly submissive. But have thought of trying being submissive myself, so did a little research & Stormy would be the one I'd chose, as I'd want someone both strong & who comes across as a nice person.)
