But for hopefully adding to the discussion instead of parroting what's already been said, I would almost want to say that its impossible to ignore either gender if you're a polytheist. But then thinking about it everyone's different. Could it be possible that a pagan never comes in contact with deities from one gender at all?
There are forms of Goddess worship - the Dianics primarily - who come to mind. They absolutely reject any need for masculine deity or polarity. I have no problem imagining them avoiding contact or ignoring it from a male deity.
There are also polytheists who acknowledge the existence of other Gods but focus their worship on only one deity. It is possible that may mean the individual will only contact or experience one deity of one gender.
