I never cared for the idea of Superman having any sort of sexual relationship at all, but with a human....I mean even is hair is super strong. I have to assume, this means his wedding tackle is also going to have some super qualities. He could likely ram an erection right through a steel door. How is that going to play out on some lady, or worse some dude engaging in a form of love where poop and blood are not so uncommon, and even if Supes lets you play pitcher instead of catcher....seems you could lose a member pretty easily with any tension?
It always seemed like any sort of sexual relationship from Superman, unless you have him dosed with kryptonite, is a good way to get killed in a horrible way. I think he should stick to super heros with similar qualities, not intrepid female reporters, or now some genderqueer twink.
This just opens up a can of worms around how exactly Superman's powers work. Does he have super farts and super burps? Is his "invulnerable" skin flexible? Is it more rigid than steel? If it's not flexible, how does he move? If it is flexible, how does it resist damage? Does he have super explosive diahrehha? Is he immune to earth viruses and bacteria? Does his biology need beneficial bacteria? Does Superman have to eat or drink? How much physical nourishment does he need? Is he completely solar powered, and if so, how does he build more tissue?
etc, etc, etc...
My biggest problem with Superman has always been Krypton. They're one of the most advanced spacefaring races in the entire universe, and their members have immense powers everywhere except under their own Sun. How does a trait like that evolve? It doesn't. There's no way you can ever make it make sense.
And if it's not evolved, that means it's engineered. Which kind of makes sense, at first glance, If you're one of the most advanced races that ever lived, why not give yourself powers that vastly exceed those displayed by most gods in myth and legends? But if you do that, why not make it work in your own home system? And even if that was somehow impossible, why not just go live somewhere else?
But they didn't. They decided to stay home on their own home planet. Which again, could conceivably make sense. We could conceive of some religion or philosophy that pushed the masses to stay home. But... mass movements don't work on literally
everyone. Because except for ejecta and a captured bottle, 100% of the species was killed in the planetary explosion. That means not a single Kryptonian went off to live somewhere else.
Which requires a staggering degree of conformity. Yet Superman himself is basically the embodiment of the American ideal of independence. Clark Kent isn't a blind follower, so it's clearly not genetic. And Krypton's culture is typically portrayed as a bit hidebound, but it's not some absolutist totalitarian nightmare, which would be the the only way to exert such an absolute degree of control over a race that's psychologically similar to humans.
So I guess... magic? Except he's not magic. He's weak to magic.
There's no way to make any of it make sense even by the incredibly loose standards of comic books. The only way to deal with it is to ignore everything.
