Personally, I'm surprised that there aren't more lesbian characters on TV. Every time there's a lesbian episode or plot on TV, it gets attention.
However, I think that the attention comes from both male and female viewers. I'm sure that many men watched "Xena: Warrior Princess" because Lucy Lawless and Renee O'Connor were hot. But I'm also sure that many women watched "Xena" because of female empowerment.
Anyway, I believe we will see more of this.
