Well, most of the geldings I've worked with have been moody and large pains in my butt. The mares I've worked with have been sweet and rarely marish. But despite the bad rep that the geldings have shown me I'm still on the wall about which gender I prefer. If I had to really choose between the two I'd have to pick mares because the horses I've bonded most deeply with have all been mares.
