My impression is that women were expected to remain virginal until marriage and have no affairs outside of marriage while their husbands were off cavorting with boys and other women, but we all know what happens when you assume. (Plus, it seems kind of odd to me that this attitude would exist in a setting where the more general attitudes about sex and sexuality were so open, relatively speaking.)
I tried poking around on wiki, but I couldn't find anything, and I didn't have the first clue of what to google.
