Remember how Mike Pence basically avoids being alone with a woman unless his wife is present? As ridiculous as it sounds, that self-preservation strategy got him to VP.
It minimizes the chances of (a) false accusations of inappropriate behavior, and (b) adultery.
It makes me a little sad for the limits it imposes on my friendships with women, but I consider the tradeoff very worthwhile.
EDIT: Just to clarify, I'm not suggesting that everyone should adopt my policy. I'm just saying that in my particular life circumstances, and with my particular ranking of concerns/values, it's a tradeoff that I find worthwhile.
