Before this gets into too much of a debate, let's remember one thing.
This is a fiction story.
Wendy, and Kae, as the writers control the actions of the characters in their story. They apparently believe that, under the conditions they created, Lois and Clark could use sex as a comfort tool. I don't.
But it's not my story. They invite our opinions with these comment threads, but the bottom line is that it's still their interpetation of events that is being portrayed. You must take the story as it's delievered and base your enjoyment on how well you can 'get into' what's happening.
No one doubts the talent of the two young women, but ultimately each gentle reader will take from the story what they will.
Tank (who knows he has certain 'prejudices' when it comes to Lois and Clark that don't always jibe with what others think... and that's fine too)
