Yep, been there.
Ive had plenty of stressed fems throw a male banana flower.
Ive had what were traditionally straight fems stress into full time hermaphrodites too, at least thats my observation of what had happened. Wind blown pollen may well have played a part though the other characteristics didnt change noticably.

Also, on jurassic park, all the dinosaurs they created were females. But like one of them said, "nature will find a way" and sure enough it did, eggs were found!
