I'm a guy, and I grew up pretty rural and it was not terribly uncommon for some of these ideas to float around. Many girls I knew were not taught anything at all except all the various religious negatives about women's reproductive bits and as they hit puberty had no idea what to do.

A few teachers in my high school took it upon themselves to provide a sort of underground sex-ed for some of the girls who couldn't get parental permission for the official classes.

There was a fairly large Pentacostal group at my high school (you may recognize them as guys dressed like 1920s farmers and girls with long hair and all denim floor length skirts) and this group of teachers were a virtual life-line for those girls. [1] [2]
