Perfectly willing to speak beforehand. I agree it gives you a good deal of insight into the person. But that should be acceptable via blocked #. If you needed to cancel (as another poster mentioned), I think that's where e-mail would come into it.From a provider prospective, there's a few reasons I like a contact number, for my safety, it's quicker to talk on the phone( at a time that works for you privately!) and for me I think you can tell a lot about a person by the sound of there voice and how they communicate with you.
Now there our times when I've let phone numbers go, if I get emailed from a work address. Or I reputable provider can vouch for you.
BUT!
If your going to spend a hour or whatever with us intimately, why wouldn't we be allowed to talk to you briefly before hand?
Also providers aren't going to call your like a mistress would? So you wouldn't have to worry about getting busted( 9/10)!!
Thanks.
