He wasn't gay. That one time with Sasuke, that kiss... was because some kid pushed him. Never again.
He didn't like guys. Sure, he'd looked at Neji in the hot springs. He looked like a chick. He had to check. He didn't mean it that way.
He never seriously thought about men 'that way'. He saw Gaara as a brother. That one... look they'd shared when they were in the midst of fighting had been the result of rage and battle andreliene. They didn't do anything.
He didn't watch guys go at it. Yeah, he'd seen Kakashi and Iruka necking in the classroom once, but it wasn't like he'd stopped to watch. There were some things a kid does not need to see, and watching your former and current teacher kissing is one of them.
He might have doubted all of this, taken all of the above as excuses, not evidence. But he knew he wasn't gay. Bi, maybe, but not gay. Because as soon as his eyes met hers, and he saw her again, instead of memories of boys he'd fought along side with in the past... As soon as he heard her voice again, everything was right.
He was either straight, or bi.
Because Haruno Sakura was DEFINATELY a woman.
