So what IS the lesson from this maaisa of Avrohom not having looked at Sara?
I believe MR included that in the OP.
This is the ideal that the Torah wants. Avrohom and Sorah are the model for a yiddishe marrage. Just like Avrohom never looked at Sorah and certinly never socialized with her, so too we should strive to reach this goal with our own wifes. Halevai if any man could say that he didnt know his wife was pretty becuz he never looked at her.
