A childhood belief about condoms

I once asked my dad if we were going back to the condom. I was trying to abbreviate "condominium" and wasn't familiar with "condo". He told me that we were not going back to a piece of plastic that grown men put their penises in. He wouldn't explain why, and I was confused.

Later, during sex-ed. We were taught about nocturnal emissions (wet dreams). So I put 1 and 1 together and asked "so do I have to wear a condom all night so I don't wet the bed". The teacher had a baffled, but surprisingly straight, expression on her face.
