Have seen it done in 3rd world countries, Also, when in an unnamed African nation, millions of condoms were sent to combat aids. The recipients were using them as water bladders to carry water to the village from a local water source.
Unsure if they were ever used for ‘relations’ or not.
Sixty years ago my Agri teacher in high school told us about using lots of condoms in WW II. They were placed over the ends of their M-1 Garand rifles to keep rain and trash out. If in combat they did not have to unplug the bore.
