This is the "taboo heat taboo." It is the social prohibition against acknowledging the thermodynamics of desire. It is considered morally primitive to say, "The fact that this is wrong makes it right for me."

A taboo is not merely a rule; it is a sacred prohibition. Unlike a law, which is enforced by the state, a taboo is enforced by the collective soul of a community. In ancient societies, taboos protected the tribe from spiritual contamination. Don’t eat the sacred animal. Don’t touch the chief’s crown. Don’t look at the shaman during the ritual.

The "taboo heat" is most safely experienced in the mind or in consensual roleplay. A couple pretending to be strangers in a bar is using the taboo of "infidelity" to generate heat, without actually betraying anyone. This is healthy. Acting on a real power taboo (e.g., coercing a subordinate) is not.
