took my own but she had some which she put on w/o discussing

Newbie questions are best asked on the newbie board.

But I will answer, providers normally have condoms but it is not a bad idea to bring your own. Most providers will want to use theirs even if you bring your own but once or twice a provider forgot to bring some and I was glad I had some. If you bring your own make sure that the box is unopened and not expired.

in am incall situation the provider will usually take care of the condom as they don't want a bunch of used condoms and condom wrappers lying around or in the trash giving away what she is up to. If I am disposing of it I just flush it and pack out the wrapper.

I never not had the provider put the rubber on. It is their safety after all and they want to be sure it is done right and it is a proper fit.

Newbie experience

My measly two experiences indicate that providers bring the condom and they put it on me. I just pay for it

I never carried one but your post makes me think: maybe I should

Also never had a provider say she didn't have any.  As has been said, most of them prefer to use their own.  They may have allergies to certain types, or just have brands they prefer over others for their own reasons.

If she is doing incall at a hotel, she will usually flush it down the toilet and collect the wrappers and dispose of them some way.  If she is doing incall at her home, prob same thing.

Most girls will put the condom on you, I have had to help on occasion, as she had it backwards, but normally it will be done for you.

refused to go along after the box has been opened (thrown out, actually), as long as the wrapper is sealed and date stamped. A couple of times a girl has called ahead to ask if I had one or said she was glad I did because she was down to her last.

I remember an evening several years ago where the lady had apparently dropped hers in a cab in NYC.  Not a complete loss, BBBJTCCIM twice,  I knew her well, though, and I doubt you could ever count on that as a newbie, even with an established provider.  Thus, always remember to have this base covered, and have a couple at hand, just in case...

having some prevents certain scams & avoids emergencies so I always bring a sealed 3 pack.  I know a lady is within her rights to insist on using hers (if she has them).   Once my ATF asked me to stop & pick some up...  I was already on the road & was inconvenienced and especially caused me to be late (was not an issue with her but was with my time window).  I had to settle for what was available, not the premium kind I prefer...  so again, best for me to bring my own.
