I have not had a working number for this business after the first few months. I prefer email because if a guy calls he will still have to go back and fill out the screening info. I know give my number out when a guy is verified. I would say one phone call leaving a message is enough. It boggles my mind how some providers make any money at all when they take 3 days just to return a call!
You email me and see how fast you get a response...less than an hour provided I am not sleeping or my mouth is full.
