Best to ask the actual provider hon ...

... if her reviews state a service, her ad promises GFE or she promises you a certain service, you by all rights should ask her "why not me?". It shouldn't matter what the client looks like ... fat or thin ... young or old ... handsome or not so much, but if his hygiene is a bit suspect I let him know (no excuse since I always offer showers before and after play) ... cut or uncut , clean is clean (amazing how many have no clue why there is a washcloth and how to use it). Feel free to ask a provider if she provides the things shown on her review profile and in her reviews. If she knows there is a discrepancy (which she should have corrected), she will tell you (if she is honest and not just trying to get you in the door under false pretenses).

I think a lot of guys embellish their reviews. I find this particularly true regarding BBBJ, kissing, and CIM. If every review indicates certain services than I think you can be comfortable in anticipating it in a session. But if the provider only has a couple of reviews or if the reviews differ wildly than I think you may or may not receive those services.  

If you are clean, on-time, and don't nickel and dime providers I think you will do just fine overall.

Even read a review that said "she put a cover on me and started a bbbj" LOL. idiots like that piss me off

I think your best bet is to give a tip up front smell good look good and make it clear to the provider your clean. I cant think of a well known provider that didn't let me service their dicks raw. Im talking Lola Malone,Vannila,Kim Cummings,Leather,Ednita,There have been times that it has happened but not often.
