Unlubricated condoms are used for practicing survival skills. If he was doing that in another country, and he is a survivalist/prepper, he might use them for that. If they are lubed, he was looking for some fun. I think the US Air Force issues condoms as part of their survival kit. They stretch a lot and can be used to hold water before or after purifying it.
I have a long time interest in psychology, specializing in relationship dynamics for 30 years.
