In my experience, she should be well prepared if she is a reputable provider.  Better have it and need it and not have it, as the man says, but I've never brought my own and never had an issue.

Most reputable providers have condoms on hand.  You would only need to bring your own if you need something special that she might not have like non latex or king kong size.

If she expects gents to bring their own covers, it should be mentioned in her reviews.

I've never seen one who didn't, but I have read some reviews where the guys had to stop to get some or had to go back out. It couldn't hurt to bring some along with you just in case, especially if you prefer a certain brand or fit. Just make sure they are unopened. Most likely, you won't need them though.

Exceptions happen, but usually when you need larger ones, or special circumstances.  I have read reviews of providers that had the client pick some up on the way, but IMHO, those were lower end providers.  If you are going to want to use the ones you bring, they need to be in an unopened box, otherwise, you are outw of luck.

they don't have your size, style, etc. So, if you are particular or have a particular style you like, you will need to bring an unopened box along.

we trust the kind we buy and usually have several to choose from so once things start to happen we know the exact kind we need to use for you.

against some scams...   or unfortunate oversights.  
Generally the lady will have them & if they do they will likely prefer to use their own.  I respect that but have never been refused to use my own (premium extra cost) but I wasn't pushing if they didn't.

when you go to a restaurant..do they have plates, forks and spoons? you can figure the rest out im sure..

The lady many have just run out, as I've experienced....

Always good to be prepared!

And the ladies will appreciate it too....
