I find the general description of this lifestyle considerably more useful and appealing than the cuckold or hot wife genre for at least some stories. However, there is one nagging question. Do stags, by definition, remain faithful to their wives who stray at their direction, content to facilitate things, or do some stags get strange, even if the emphasis remains on the vixen wife's fun? In other words, is this a loosely defined category, or is there a very precise, specific meaning and something similar except for the man getting it on the side would be distinct nonetheless from stag/vixen?
