Review of Mary & George

Apart from this series being the perfect peice of historical drama there is one glaring monstrosity. Of the 5 episodes watched (looking forward to the others), there has not been one sexual relationship of the hetro kind. Not one. No affairs between men and women. Not even the insinuation of one. Why? With everything based around George and his mother attaining higher status and doing whst they must to get there, it is clear in the beginning that George was in love with a serving maid. He did not prefer men until forced to use this as a way to advance himself. So why is there no women involved with George?
