Are condoms something that I should bring?
 
What about other stuff like lube and clean-up stuff?
 
Is it common to bring stuff with you/

and there "should" be no reason to bring anything but the proper donation and a good attitude, BUT "just in case" I usually make sure to keep an "unopened" three pack of condoms in my car as insurance against the unlikely event the lady is not properly prepared with condoms on hand. This way if she tries to pull the "oh I am sorry we can't have sex because I don't have any condoms" you can simply run out to your car and get some.

 
Actually to be honest, I usually keep a "go bag" in my vehicle anyhow, not just when visiting providers.  I am the kind of guy who is likely to hop a plane at a moments notice and having a shaving kit and a couple of changes of clothes with me at all times saves me from having to buy all this kind of stuff if I find myself waking up in a different state or a different country because I felt like "going somewhere" on the spur of the moment the day before.

should all the props for a shoot...

While a professional escort should definitely supply her own condoms, a professional model does not supply her own props for a photo shoot. They are supplied by the photographer or the customer.

but your advice is as clear as mud.  

 
She is NOT a "safe and professional model" and for the purposes of his question there is no "shoot". To imply otherwise is confusing the issue. He is going to be seeing an escort for sex, he wants to know what preparations he should make. He has no delusions that he is seeing a model for a shoot. If conflating the two makes you feel better from an advertising perspective, that's fine, but it has ZERO bearing on the OP's question.

 
Folks I know many of you trying to adapt to the post FOSTA/SESTA world, but let's try to provide advice to the newbs that is actually helpful without all this speaking in code. It's no more useful in court than an "LE check" and it really does get confusing to people asking straight forward questions.

Those of us who already know the answer probably didn't have a problem understanding what Veronica meant: both content and trying to avoid certain overt statements.

Since this is the Newbie board, perfectstorm's and GaG's criticisms do make sense. Some newbies might have figured it out but others not.

I will not add to the confusion by saying that the "photographer" should make sure that his "camera" is fully loaded and has fresh batteries so he can get off at least one good "shot" or maybe even multiple shots during the modeling session.  You don't want to waste a good photo op!!
