For the Love of Shame
There's a reflex to conceal ourselves especially in regards to our sexuality. This reflex is called shame.
Some would point to this being proof of an inherent type of sacredness that's tied to an individuals sexual value. The shame that surrounds sexuality is a protection from objectification. We hide ourselves to keep from being used. Sexual intimacy is a private act for this very reason. Love demands this protection in order for a healthy sexual interaction. Shame aids love in this case and is a positive.
Others might say that any feelings of shame are simply a result of arbitrary social rules. That the hiding of our sexuality is a result of something or someone trying to control us. Shame isn't a justified instinct then, but a way to keep us bound. If we eliminate the shame regarding sexuality then we can be more free and happier as a result.
As liberating as the latter point may be, I can't help but think we like to conceal ourselves. At the very least this comes from the necessity to protect ourself from those that don't care about our well-being. Also, we can maintain the perception of our value by shrouding ourselves in mystery. Hiding parts of our person helps us keep a sense of our inner sovereignty.
The feeling of security concealment gives will inevitably be a desirable factor in our personal lives then. Because of this, we may actually like shame more than we will ever allow ourselves and others to know. We hold it dear, because it shields us. For this reason expressing anger towards it is probably cheap signaling in most instances.
