Yes and no at the same time.

While Kirito is obviously a male, he is given a female avatar in GGO because of a system error when the AmuSphere headset was interpreting his brainwaves. What results is him being in an extremely attractive female avatar's body (with male sexual organs), an incredibly rare occurance. In fact, as soon as he spawns, a man offers to buy his avatar from him for millions of in-game credits.
