Maybe I did misread you
Anyway, My impression of most religious conservatives may not be any better than yours since I ain't one.
Based on observation I tend to believe that much of the sex outside marriage concern has gone by the wayside particularly when it involves mature males and females. They certainly believe in keeping marriage vows but a lot of the other pickiness when out with the unshorn hair and the ban of makeup.
I don't doubt that is still considered a sin but what the heck, they are irrevocably saved by grace.
