Nude male swimming in the USA
There are literally hundreds of period specific articles we could post that discussed school or public recreation programs wherein boys were required to swim nude as opposed to the girls, who always wore suits. Prior to the 1970s, this was standard practice and thus, such articles are unremarkable and restate the obvious. Articles we have posted here [see url] demonstrate double-standards in that they show young male nudity in public newspapers and magazines, or, evidence mixed-gender access to the swim areas while the boys conducted the courses in the nude.
