Add to that -another taboo is money in an email , text , or phone .

then why did you email me asking if i "suck dick" for a living? if you can demonstrate that knowledge here then I'm not sure why you couldn't demonstrate such knowledge in your inquiry?  

Re: Discretion in emails.

its for privacy and too keep us all out of the doo-doo- most pros sites state the donation rates for their time.

Have you ever booked a provider before without TER reviews? Or have you showed up to a provider, paid her the rate she asked for then have her tell you she does not do this, that and the third? Or upcharges? Going over the sexual menu, boundaries, restrictions and rates in writing and before the provider gets paid is absolutely necessary. Most providers don't have reviews either because they are new, de-listed themselves, have a no review policy or because most clients don't write them. Every provider, unfortunately have different service levels and have their own definition as to what FS and GFE is. Some providers will have different or confusing rate structures. Some providers won't see certain races or ethnicities which is not explicit on their websites so all the "back and forth with unnecessary banter" is very necessary.

SB's have less to worry about because they are not advertising to random men, but rather looking for an arrangement with one, or even a few men.  Men who have girlfriends often help them out financially, and most SB arrangements are not compensated by the hour, which is what distinguishes providers from SB's.  Never heard of an SB getting busted because sex usually doesn't ensue until the SECOND meeting and no money was exchanged on the first meeting.  It's more of a meet and greet to check for attraction and compatibility.  At least the way I have approached it in the past myself.
