Nudistische Schulerziehung

Read here...u must translation

 

I can't say anything about swim class at school, because my school didn't have a pool or swim classes. But yes, the YMCA's used to have nude swimming back in the day, However, by the time I was a kid that seemed to have gone away, as all of the Y's were coed by then.

 

I grew up in East Germany, back when it was still the GDR. In some schools, it was common to conduct swimming lessons naked. I was in first grade at a very large school with a big indoor swimming pool, and we started learning to swim naked there.

In many schools, swimming lessons were taught naked for the first three years of school.

At my school, it continued until the end of sixth grade, until I was 13 years old.
