Oh damn. I must have been thinking of New Cutey Honey. That just ruins the joke. Honestly there's a pretty weird split with the franchise where it's like 50/50 basically-porn/Mega-Man-but-girl-fighting-catgirl-gangsters. The original '70s show falls into the latter, and apparently so does Flash? Although wikipedia is... troubling.
The protagonist of the series, as with other Cutie Honey media, is Honey Kisaragi. However, unlike other Cutie Honey incarnations, Honey is not an android but possesses a fully functional human body including reproductive capabilities. Consequently, she is indeed a 16-year-old girl at the beginning of the series, not a robot posing as one.
