I used to believe that us boys grew condoms, and I could never figure out why mine had never grown yet. So I told my friend about it saying "How come my condom hasn't grown yet, but everyone else's had?" and he couldn't stop laughing and I didn't think it was funny at all! But he explained that you have to buy them and put them on for sex. And I didn't believe him so I asked both of my parents about it and they agreed with my friend… afterwards with "the talk". How embarrassing!
