Is Kira gay?

I always thought Kira had the "strangest" story of all fukutaichous. The way Gin always treated him was very suspicious. Even the third ending theme of Bleach (you know the one that each ending was one squad?) of the third division is really odd. Gin takes Kira in the middle of the night to the thrid division barracks.. Very suspicious XD

And then there's all those episodes where Kira shows JEALOUSY because of Matsumoto... He says to her a lot for her to "leave Hisagi-san alone" kind of thing...
