David flirted mildly and when confronted with the prospect of physical action, stepped back. Ruth made a profound and repeated emotional committment with a certain prospect of bedroom action before drawing back. David enjoyed a single stolen kiss, whilst Sam's grubby prints are goodness knows where. No real equivalence there I'm afraid.

The subtext of the plotline seems to be that the envelope for "moral" behaviour for men is much smaller than that for women.

It doesn't seem fair.
