I don't think it is the sport that matters so much as the person.
For me, I am a big fan of females. They are more resilient, independent, mature faster, not as soft, and want to please without clinging.
The boys I have had have generally been clingy, have to be with mommy types, who take too long to mature mentally, don't take as much to get upset, and because they are more clingy, don't tend to want to work distance as easily as the girls.
Now, that's not saying all males are that way, but of the ones I've had, that's what I've gotten.
