I wouldn't count on that - at least not in a strictly online sense. Perhaps if you meet one in real-life, and he sees you as what he wants - the physical/emotional/mental combination, then he'll want to invest that time and patience. But online, it's too simple to give up and look for another sub. And asking an online Dom to 'jump through hoops' very early on (as he might view it) could easily drive him away, even the ones who might have been worth keeping. Keep an open mind, mg. You may find yourself surprised. And ask other subs who have been here a while - even if they have no experience with that particular Dom, they've probably formed some opinions based on watching his interactions with other Doms and subs. Feel free to PM me if you'd like - but I must admit, I know nothing about the Doms who hang out exclusively in the chatroom, since I'm so very rarely there.
Heehee! I wish it were me, cause that's great advice! (I think it was Tojo, above.) I would add a note of caution: some Doms will offer to 'mentor' when what they really are looking for is a subbie (or six) to play with and figure that paying the price of listening to her is worth it. Submission is so emotional and mental...beware of those who want the fun of having subs with none of the emotional and mental involvement. I can just hear it in my head: "yes, yes, it is hard to find a good Dom...how about I let you show me what you're willing to do so I can gauge your readiness...now buy a webcam so you can torture your nipples for me tomorrow."
Bah.
