Thanks I.
Clark of LST world doesn't know how to block yet.
I will address why he didn't come busting in at the first sound of her distress in the next chapter.
And Canon Clark goofed, basically. I like it when he screws up, because despite not being human, he is still error prone.
He didn't have the same general caution that Clark carries around with him always (the abused-spouse eggshell thing that Lois mentioned) despite knowing that she needed special handling. He's just used to dealing with a more resilient Lois.
As far as LST Lois and clark - yes, Clark and Lois have good times, and they have not so good times, and Clark is very careful to make sure he knows how she's feeling before attempting to get close.
