Met a lady on SA several months ago.  Very little back and forth banter and set up MG right away.  Set up BCD soon thereafter and have seen her about twice monthly over the 4 or 5 month timeframe.  Here is why I think she is or was a pro:
1.  No kissing.  I love to kiss and always make sure my breath is fresh.
2.  There is no undressing her.  She comes to hotel, makes some small talk and then says something to the effect "Are you ready?"
3.  Sends me nudies and selfies.  Background is more frequently then not a hotel room.
4.  Goes for the BBBJNQNS with hand action to get things started.
5.  Constant emails regarding when is the next visit

What do you think?

Or a overly cautious lady thinking kissing is to personal. Doesn't want to catch feelings..i was seeing one like that for L.T. sugar. Was my unicorn until she started on with the "ya know kissing turns me off b.s." then while doing daty I'd introduce a finger, and then she'd reach around her leg and pull my finger out..things she'd never said anything about before now became issues..it had run it's course..shed also would never go out with me in public on dates, everything was discreet. BCD only..and only for an hour. So i deliberately made it known she wasn't keeping me happy with her crap..well, she ghosted me..lolo so, these END fast..

I mean really.  The arrangement you have with her is what it is.  Enjoy it or not, but I see no big need to label it.  Hell, if you want to know if she's a pro that badly, ask her!

Who cares?  She rocks you and you get handled a couple times in an hour.  You are good to go.

Some just know it.

... do you like fucking her for the sugar you provide?  

If the answer is yes, then don't worry about her "occupation" and enjoy the rides.  

If the answer is no, then just bail and find a replacement. Don't worry, there's always more around.

Ok why do you care if she's a pro- you're on a hobby website and have clearly seen several providers.

Speaking only for myself, I play in the sugar bowl because I don't like the 1 hour time limit, and some of the other things that go with seeing a pro.  With a SB, I rarely feel that she is doing a "job".  If it does feel that way, that will be the last time I see her.  

Yes, but on SA you can negotiate even if she's a pro.  If you don't like the deal, move on.

Or he thought he bought a vintage Porsche only to find out it was a run of the mill Audi or worse a VW. Lol

SBs are pros. They are having sex for money. Some admit it to themselves and others don't.  

Obviously I don't think that there is anything wrong with that given that I am on this site, but when the topic has come up with SB's, they have all admitted that they are engage in escorting-lite. I wouldn't judge a women who dips her toes in both pools any differently than one who sticks her toes into only one.  

There are differences of course along a spectrum. SBs tend to skew younger (and sometimes flakier); they tend to be much more comfortable with bbfs; and they are of course interested into longer-term, longer-date relationships. However, all of these things happen with escorts too. There are also many SBs who are young but mature well beyond their years.

Several folks overlap between here and SA in my area.  Some even use the same pics, which seems a bit lazy / foolish to me.  The ones I've noticed tend to show up, get a flurry of activity, and then just fade (not log in), so my guess is that it is not that effective a channel (or else maybe super effective, but somehow doesn't feel like that).

In the last couple of days, I've seen about half a dozen more show up in my area.  I may not have noticed the clever profiles, but the half-clever profiles use different pics but the same handle so, well, not that clever.

Not sure how well providers do on SA if they act like providers.  At least for me, SA is attractive because of the non-provider aspects of the whole gestalt, so while I've met with folks who I knew had a provider presence, as long as it's in the background it's cool.  When it hits the foreground, it breaks the illusion and becomes less interesting for me.  I don't view it as my business what someone does when we're not together, and I don't judge it, I only really care about how things go when we're together (and interacting when not together).  Yes, everyone needs at least one good rationalization to get through the day.  Just how I roll, YMMV obviously.
