When I go to the local shows around me, there are maybe 2 male riders out 150 riders all together, so it is hard to find attractive ones.
In general, I like male riders, and would date one, if we clicked. We would have horses in common. Although there is a down side. If he is competitive, he may act competitive, as most males do. Riding with him may not be as enjoyable because of that.
But, there are different people out there, so this wont be the case with everyone!
