I am an English female, and middle-aged. Back in the 1960s, my friend and I (being really embarrassed about periods and sanitary pads) thought that if we had to wear THEM once a month, condoms must be for a similar function in boys! We actually believed that boys had to go and buy condoms on a regular basis!!
A childhood belief about condoms

others believed things like this
- I used to believe that condoms were weared by girls and boys
both. And they both have penisAnon - I used to believe the Beastie Boys were a boy band. Well, the name sounds similar to Backstreet Boys!Anon
- I never knew why boys had to lift up the toilet seat...until my friend told me that boys had bad aim.Anon
- When my mom was a child, she thought that while girls had periods, boys had hemorrhoids!Anon
- For years I thought that spunk was a male period and that boys spunked once a month - Yeah right!— Stupid Child
- When i was a nipper my mum told me that condoms were sweeties for grown ups - i believed it for years!! :-)— LCF
