I wonder who first looked at Maud and thought "Yeah, I'd hit it." What's there to gain from it? She doesn't cry out when she… "culminates", in the words of a certain fanfic. She doesn't seem like the type who'd move around too much, either; I imagine it being akin to making love to a pillow.

…Wait, am I seriously taking an analytical approach to sex with a cartoon horse? The hell am I doing with my life?

How sad it is that we are attracted to horses. Then again, they were designed to be… appealing, to say the least. Of course, Personality comes into play as well.
