Lois for sure pegs Supes. As she should. He lives a life where he’s the strongest person in the room, no matter where he goes. He always has to be the big strong man with the weight and responsibility of the world on his shoulders. So, he likely has developed certain kinks as a result. A man with all that power and responsibility would almost certainly be submissive in bed as an escape mechanism. Hell, he probably has bondage gear laced with trace amounts of kryptonite or a red solar lamp so he can really feel it. Superman likes to get pegged, and I’m fucking here for it
