Narusasu - SasuNaru - Yaoi - gay - Naruto - Sasuke - Uchiha -.
Since the creators of Naruto have not made Sasuke doing homosexual acts, I will vote him as not gay. However, in my opinion, the closest person to being "gay".
Is Naruto gay for Sasuke and is that why he left Sakura alone to go look for him? How would Naruto franchise be any different if Naruto and Sasuke were gay?.
