Well, it's certainly a male, if not a hermy.
The pollen has been released, so if it is a hermy and not just a male, your bud will now have seeds in it, which isn't great but isn't the worst thing ever.
If you have SEEN white hairs, you may as well keep it.
My first plant was a hermy and after fully growing I got a week's worth of bud from it.

(By the way, I had a week off work, and I don't remember any of it)
