Correct, definitely male stamens.
You can try and remove any more that you find, but looking for and hopefully finding any will need to be done every single day, as even one missed "banana"/stamen will result in a lot of pollen being released, causing seed formation everywhere. If the stamens start appearing in great numbers or increasing frequency you will either have to isolate this plant and if no room is available for it, choppity chop chop may be your only option, to "protect" the rest of your girls getting fertilized and seedy.
Generally once there is one, they will keep appearing and you will need to be very vigilant and examine each branch and each flower in great detail to find any/all stamens before they open. Sometimes they are unstoppable, other times they appear randomly and in very few numbers, and I have grown a plant that had only one single male flower growing from the main stem of a 5 foot plant, but this one flower was responsible for 150-200 seeds found throughout the entire grow, with most being in the flowers next to the male flower, however seeds were found in plants 10 feet away too, showing how mobile male pollen can be. Apparently pollen can travel up to 100 miles on the right winds, however I am not sure how they conducted this experiment.
Hope this helps, and I do know how heart breaking it can be to have to cut down a beautiful plant that you have been nurturing for weeks already, but sometimes, this is your only option. Losing one plant is far better than having 2,3,5, 8, 10, 20 plants that all have seeds.
Remember too, any seeds made from hermaphroditic plants' pollen will carry dominant genes for this same trait, meaning this plant isn't even a candidate for breeding purposes, but a cruel twist of fate. ,........... Organoman. ........ Good luck with this one.
