Kudos to Jtor for spotting this: sex ed manga Naisho no Tsubomi (Secret Bud, as in flower bud) is going to be made into an anime, according to a manga cover photographed on EARL.BOX.

This isn’t the first time that a sex-ed-related manga got turned into an anime, actually. According to the display on Marvelous Melmo at the Osamu Tezuka exhibit in San Francisco, Melmo was supposed to be a sort-of sex-ed guide for girls - but remember, it came out in 1970. But it WAS made into an anime in ‘71.

But from the look of it (see Jtor), Naisho isn’t anywhere near as subtle with its teachings.
