A bit of info
a Hermie, is a plant which exhibits both male and female flowers, so one branch would be full of female flowers,
and one branch could be full of male flowers, that is a proper hermie.
When you see your plant spitting bananas, it is your plant showing inter sexual characteristics most likely, but not always
due to stress, and there are good chances you will find a few premature seeds due to pollen being created by these bananas.
Your plant can self pollinate even without showing bananas on the surface, there are good chances there are bananas within
the buds themselves. Just check for seeds when you're done.
