I watch women's MMA, as it's featured on the same cards as men's MMA. It's often not as good as women's MMA is still in its infancy compared to men's MMA, but there are a few really exciting female fighters out there. Tate, Holm, Rousey, Zingano, Cyborg, Jedrzejczyk, Namajunas, and a couple of others are fun to watch, moreso than many male fighters.
Aside from that, I can't say I watch any women's sports. I catch a bit of women's tennis on the odd occasion, but I'm not a big fan of tennis anyway.
What about you?
