No harm to bring one in your wallet but chances are she wont trust it.
In all my escort experiences, I've only rarely met an escort that was scarce of condoms, in 2 of those cases they were down to their last one and in the other case a lady I had met before was running low, and asked me to pick up a few packs at the shop. Very unusual, but shop was between the landmark and her apartment.
Was really disappointed visiting a popular well hung ts and she was down to her last one and I didn't have one in my wallet. There was a full pack in my car but parked too far away.
To anyone that doesn't like me here.
I hope you need to pee 3 times tonight, but that you only wake up twice.
