Honestly, I think the Richie case is why they need to be careful with same-sex pairings and not just doing it for the sake of it. Yes, on paper, Richie might have felt more comfortable with a male pro, but in addition to the other male pros like Kai & Graz (my two picks for him), I can guarantee that he'd have had a better time with one of the female pros than he did with Gio. There's no reason to put two totally incompatible guys together just to look inclusive.
