Apparently, many men have never actually ever touched a tampon, or bothered to learn anything about one. [Ed. note—I could get on my high horse about this but I thought when a boy got a wet dream it meant he was wetting the bed until, like, last year.] But Cosmopolitan magazine decided to fix that by filming men interacting with tampons for the first time. Men all think tampons look like fireworks, apparently, until they get into water and turn into flowers. Also, they don't think the cardboard actually goes inside. Hmm.
Again, while women could and maybe should shame men for being clueless about this, it is a near certainty that most ladies don't know how often a typical man gets an erection every day. Either 2 or 20 or 200 times? LOL IDK. In conclusion: this is the state of sexual education in this country.
