This is true, also I’d rather like to pinch his butt more than hers. I know that in the actual fifties homosexuality wasn’t spoken of in polite society but still.
One also shouldn’t underestimate the appeal of all those artfully drawn covers of sci-fi and fantasy (comic) books on homosexual youth of that era. One older gentleman more or less told me that, while his contemporaries used to hide naughty magazines under their beds, his were out in plain view, in a nice reversal of the general trends in those days.
I’d also like my character to be able to wear some of the highly impractical and silly, yet somehow still kinda hot looking, sort of outfits Buster Crabbe used to wear in the 30’s Flash Gordon and Buck Rogers serials, because aside from the unitard, the current outfits (blue suit, black suit) seem a bit boring, more like Star Trek TNG than that really old sci-fi kind of look.
Note that the villains also often seemed to take pleasure in ripping the hero’s clothes and/or stripping him down
So there was definitely an element of homo-eroticism and/or appreciation of the male form (at least as much as they dared show such) there.
