He never says it, but his default method of problem solving is to basically ham it up and draw all the attention onto himself(then gets uncomfortable at all the people looking at him)....What's that supposed to mean?
Because I personally don't recall Kirito wanting attention in any of the iterations of SAO we see him in, per se.
People getting riled up against beta testers were met with the rather hammy "Mwahaha, I'm a superior class of beta tester known as the Beater". Then he runs off to solo again.
Going around with 1H sword, no shield(which was explicitly suboptimal until he learned Martial Arts to use his off hand, or later Twin Swords), wearing all black, etc, basically are stuff that makes him stand out even more.
Intervening for Silica...I'm pretty sure he had a lot more options than to just wade into the low level players and let Battle Healing just regenerate faster than they do damage.
Figuring out Kayaba's true identity, there's better times and places than shanking him right there.
Girly avatar...hams it the fuck up and play the cutie better than most of the girls.
He doesn't say it, or even think it, but he certainly acts like he likes attention, even if he doesn't know what the hell to do with handling the attention afterwards.
