One of the few ongoing queer characters on 1950s American television was Percy Dovetonsils: comedian Ernie Kovacs's beloved lisping, purse-lipped poet who recited bad verse on a set representing his Greenwich Village penthouse. Kovacs used this character on various shows for more than ten years.
Given 1950s censorship of LGBTQ content, Percy's sexuality was mostly hinted at, though on rare occasions he would do things like comment on a cameraman's "muscular legs" or pluck petals from a flower reciting "He loves me, he loves me not..." This clip is from the ERNIE KOVACS SHOW that aired live on NBC on July 2, 1956.
