Tell us why you're different and leave it.
Don't continue whittering on about it. If people are interested, they'll ask you about it. If they do, congratulations, you've moved onto the next stage in your search. FINDING A DOMME IS A LONG TERM PROCESS - IT WILL NOT HAPPEN OVERNIGHT. If you come into a chat room expecting to find a Domme who will come around and visit you the same evening or the next day to beat you senseless, just leave the room right now and go to #bdsm_stupidly_optomistic. After all - why should a Domme want to? She's probably already got a sub she can phone up and say 'drive over here now, I am in the mood to whack you'. So just leave it. Don't push it, and don't expect anything to happen tonight. Or tomorrow night. Or this week. Or probably this month. I'm really sorry - I know that you're desperate - it's clear for all to see, and there's nothing that is more off-putting than a desperate submissive. It's not pretty and it's not attractive.
