Can I ask a stupid question?
Why do super heroes have to have sexual activity thrown into their stories???
Since their stories have nothing to do with sex behaviors, or haven’t up till now anyway, why is there any need to identify someone as homosexual, bisexual, whatever??? Why does this subject have to be addressed at all????
Because the kids need to be indoctrinated.
To appeal to the oversexed, underserviced nerds who buy them to masturbate to them.
Who says they haven’t up until now? Superhero couplings (or at least almost coupling) go back at least to the early days of Superman. At their heart comics are soap operas with action, and romantic interests are a standard way of developing tension in a soap opera. Add in the whole secret identity thing and couplings get even more tension as the hero is hiding from someone very close to them and has greater stakes for hiding their identity from the bad guys.
The only thing that’s really changed is the level of detail. In the early days of Lois Lane and Supes it was all implied, by the 60s Spidey and Gwen Stacey it was stated but still stayed “dry” (no sex life details), by the 80s and Spidey and Black Cat we get a lot more details. The 80s, specifically The Watchmen, also opened the door for Lois Lane-esque implied but not really stated non-hetero relationships (took me a few readings to realize just how many Minutemen were gay).
So really none of this is new.
ABC tv show “Marvel’s Agent Carter” had the lead character and another women kissing.... Never watch that show again.
