I know it doesn't seem likely that Superman would just be wearing his costume around the house for no reason, but then again, the guy is from outer space, so who knows what he would do?
I like imagining Superman in middle age. Does he get a paunch and start looking like Homer Simpson in a Superman suit? Sure, he's handy as hell when there's a jar to be opened, but as in any marriage, does he eventually get on Lois's nerves? Does she get sick to death of flying through the air tucked under his arm so they can save money on airfare? Does she keep a little piece of kryptonite hidden in her jewelry box to keep him in line when he gets too uppity?
I'm not up on my Superman factoids enough to know if he even ages. I suspect he doesn't, or if he does it is far slower than do humans. So is it like one of those vampire/human marriages (see HBO's Trueblood) where the woman gets old and haggardly and the man always looks like a stud? How's that going to play out? Inevitably, people are going to think he's kissing his mother on the mouth. Eww.
