They aren't gay. Or, better put, they aren't interested in romance.
It used to be a thing where males in media lived together, and they were as straight as an arrow. Like Timon and Pumbaa, who show no interest in romance towards anyone or characters who show interest in the opposite sex.
The Odd Couple. The 60's movie starred Jack Lemmon and walter matthou. In Friends, several male characters lived together.
Bert and Ernie, afaik have not been retconned to be gay.
But not this is not the case for all characters. Ren and stimpy are canonically a gay couple.
Why do we fall? So that we can learn to pick ourselves back up again.
