Hi I wonder if anyone can advise me on the extent of seriousness about making a booking that you require by email before you give them your phone number?  They ask a question which is already answered in the profile they got my email from, so I answer them nicely but briefly, they than email about what day and where, I get back to them with a couple of options to narrow it down, saying let me know if this may work for you and then we can talk on the phone, friendly.......and then they don't get back (and I don't think its cos the times I've offered are bad for them, although possible), do you think I should give phone number out sooner?  I just wasted so much time and credit on going nowhere callers so I have swung a bit the other way but it  is so quiet I wonder if this isn't helping. Thanks

I put my phone number out there on the Interwebs, anyway. True, I get annoying texts and phone calls but it saves time.

the earlier in the process YOU decide IF you want to see them, the more you're in control. It's also cheaper and wastes less time, but your very first priority must be for you to decide if it suits you to give them an appointment, if they sound house trained, polite, are likely to respect boundaries etc. No point in exchanging 6 emails, agreeing on an appointment and then get the "I have a 12" dick, do you take it up the a**e question. Establish it early on, at their expense.
