Certainly does look like a male flower.
This is the problem with growing "bag seeds", generally they are the result of hermaphrodite plants which then result in seeds with dominant hermaphrodite genes, or if you are really, really , really lucky, you may end up with a pure male or a female that will be almost pure, but with a tendency to produce male stamens/bananas during late flowering. Keeping pollen from this plant to use in any breeding projects will just add genes that have hermaphroditism dominance, meaning you will breed a line of plants where hermaphroditic females will dominate in any offspring/subsequent generations, with a small percentage being male and an even smaller percentage being male hermaphrodites. The inescapable fact is though, breeding with hermaphrodites will lead to hermaphroditic offspring.
If you have a look at my diary "cannabis conundrums" and in week 7, I put up some pictures that may help you fully diagnose with what is going on with your plant.
It is always safer to buy fem seeds, especially if you are not interested in breeding, as now you have spent a lot of time and effort for no return, unfortunately.
At least you will have learned how to identify male plants. Your only option is to somehow remove it from your tent, unless you are interested in breeding your own line of hermaphroditic plants, however, I am pretty sure you or anybody else, would not be so inclined!
Hope this helps,.........
