If this manga wasn't initially targeted to the audience that it's targeted to, it wouldn't be hard for some to arrive to the conclusion that Naruto is gay.
This one particular bit from the manga that hints towards the kind of feelings Naruto has for Sasuke:
Subtle hints like this could hint towards Naruto's sexuality.
Basically, Naruto stated that he'd practically die for Sasuke. That's not something you'd say about your friend, but more along the lines of someone you'd die for, ergo, your love.
^This contradicts Iruka. Also, over the years, Naruto has made many friends, some of which treated him much better than Sasuke ever did. Hinata, Shikamaru, Sakura, and Neji for starters. Those few are examples of those who have acknowledge that Naruto's strong and a dependable ally to have around in the time of need.
A deeper meaning can perhaps be drawn from this.
