For many years, there has been speculation that Batman and Robin the Boy Wonder are more than crimefighting partners. They are partners in every sense, if you catch my drift. These rumours began probably with Frederic Wertham's Seduction of the Innocent, a seminal book that resulted in many comics being banned and in the creation of the Comics Code Authority, that ugly little stamp that for decades had to appear on the cover of every comic book published in North America.
I don't really have much of an opinion on this. These old stories were written and drawn and edited so quickly that there was no time for subtext; heck, there was barely time for regular text. The creators back then were paid such a miserable amount of money that they had to grind it out quickly if they were to make any kind of living.
As a story telling device, as a means to get it out the door as quickly as they could, and to keep the story moving along as fast as possible, they would use shortcuts like showing Bruce Wayne and Dick Grayson in bed together as the Bat Signal went off, rather than cut from Bruce Wayne's bed to Dick's. Waste of a panel or two. Gotta get the story moving along. It was an earlier time, a more innocent and naive time, and the creators could get away with that stuff then.
Fans kept these books and re-read them as jaded adults, reading things into them that were never intended to be put there. Many of these creators were dead or beyond giving a crap about what people thought about stories that had been produced 35 years earlier. I really don't think there's anything to it, these ongoing Batman-and-Robin-as-lovers rumours.
There sure are some unintentionally funny Batman stories out there, written as I just stated very quickly for a disposable readership. These stories, read today, can be totally misinterpreted.
Want an example? Sure! Just read the accompanying panel. A bad guy wants to kill the loved ones of the Atom, the Flash, Green Lantern, and Batman. The other guys feel badly about their women. Batman? Not so much!
