The human animal, like a pool of water, seeks balance in order to truly be something of value. Open a floodgate and there's an imbalance of pressure, and it flows to regain it. If a person doesn't find that balance, IMO, they're more likely to be truly unhappy or possibly go off the deep end at some point.
The CEO sub is a great example. He doesn't have that balance during the day, so he needs to heavily tip the scale in the other direction at night. Some drink to excess and lose control, others prefer to give up the control to a mistrees, master, etc.
Most folks keep a line between their sex life & their "day" life, so when one or the other starts to go astray, it is usually reflected, inversely, on the other side of that line. Sometimes it's a routine flip-flop, other times it builds up until there's an opportunity for release.
Enjoy that vacation from this side of the line, oasi86!
