We know Naruto likes females,its Sasuke who hasn't shown interest so far even as a chic magnet.
True enough, but we don't know if Naruto doesn't like males.
But I have another interesting piece of evidence that could clear this doubt even a bit.

Naruto really likes Sasuke. We don't know if this feeling is romantic, but he is the most important thing he has, it is his first bond.
He admires Sasuke, Sasuke was a model to Naruto, this was said in the battle of the Bridge. Naruto would even go as far as losing his own life to save Sasuke.
If this is not true love, then I don't know how to call it.
I'd recommend you to read the "Hagakure". Samurais used to be gay back then, it was not anything strange. It was not a perverted feeling, these kind of feelings used to start with "admiration".

Curiously, Hagakure means "Konoha-gakure":
Hidden by the Leaves
