With much prodding from his concerned wife, Shining Armor signs up to see a sexual counselor. Shining Armor's sure he doesn't need it, though. What sort of issues could he possibly have?

[[spoiler:[[RapeAsDrama Among other things...]]]]

And most of the motivations behind the mares' actions aren't tied to their gender.
