If Harry & Ron were gay, they wouldn't drool over Ginny and Hermione respectively.

Anyway, Alfonso Cuaron envisioned Lupin to be gay, but Lupin/Sirius fanfics had been around long before the film was shown. That can be comparable to Kirk/Spock from Star Trek.
Still, I didn't like Lupin/Tonks and their offspring. The age gap was too big, for one, and Tonks was Sirius' niece, making R/T one generation apart. Charlie and Tonks might have been better if they moved in together.
