Since I haven't yet grown the balls to see a FS Provider just yet, I'm going to start with FBSM.  Did my research and found someone I am going to try to schedule with.

While doing my research, I noticed in many reviews for FBSM providers, the client often doesn't give the provider the donation until after.  And in some cases, they even mentioned handing it directly to the provider.  

What is protocol here?  Would it still be best to drop it in a conspicuous place (in an envelope) when I arrive or is it best to wait until after?  This is a very well reviewed individual so I'm not worried about her running off and some schmuck coming out of the closet (so I'm not worried about taking care of it before).    

Also, I can't believe that under any circumstances it's good to hand it directly to them, but maybe I'm wrong for this type of service (since we're dealing with a HE, but not penetration).  

Anxious to finally pop my cherry and this doesn't seem nearly as intimidating.  LOL.

I always place it in an open spot at the beginning of a session. Bathroom counter, dresser, night stand or whatever. I'm also a newbie and only see well reviewed providers so I'm confident that it isn't a set up. I will say I've noticed something lately.... the provider that counts the donation before the session is usually more business like. The provider that pays it no mind is usually more relaxed and "fun". Personally I would never hand it to them directly. Don't really have a good reason for that other than an episode of Law and Order SVU where the cops busted in as the "john" was handing over the cash. Stupid? Yes. Better safe than sorry? ALWAYS!! HAve fun.

Say for instance that this takes place in a studio or place of business type atmosphere. I would be inclined to offer the standard fee up front, most likely in hand.  Any extra extras such as oral, etc. that would incur additional fee would be taken care of at the end of the session, along with any tip.
It's a place of business, it's ok to have money change hands directly.

If on the other hand it's taking place in a hotel or home setting, discretion is the rule. Plain envelope, placed in plain view, again containing the standard fee, with ex ex's and tip to be settled later.

If it's in a studio and you want to play it safe as to not offending her by handing her open cash, the plain envelope does the trick there as well.

But definitely, if home or hotel, place the envelope on the table.

and follow that to a Tee.

If she does not have instructions on this, then leave an envelope before the session on some surface where she will be sure to notice it.

This will be more of a "business" environment.  It just seems like there are different "rules" for this type of service based on what I've read.  I do agree that you're obviously going to have to fork over more money at the end if you negotiate some extras.  That won't apply to me here because I'll be too busy not trying to lose my load prematurely.  

Thanks to all for your help.

Agreed...the "protocol" depends on the person you're seeing.  Usually their website will make mention of this issue.  Personally I do not like to make an issue of donation and feel that counting it in front of a client is not only uncomfortable but a bit tacky.  I'm fine with having it handed to me and often times that is the case but sometimes the donation is left on the coffee table or dresser in the treatment room which is also fine.   Regarding tips, don't feel like you have to leave one as the rates set should be fair and adequate.
