The reason he shows no intrest in women is because he is far more focused on revenge and has no time, energy, or tolerance for women. Later, he becomes friends with Naruto but still shows no intrest in Sakura. Therefore, he is labeled as gay by the people who are ignorant and foolish haters that don't understand the difference between a friendship bond, and an actual realtionship. They also choose to ignore the obvious fact that Sasuke is pre-occupied with his ambition. Calling Sasuke gay, is foolish and arrogent. People like that need to frow up. U_U
