The Structural Origin & Minority Stress
Long before the first bad relationship arrived, the wiring had already been laid. Growing up queer in an environment where your full self isn't welcome teaches you adaptation before you ever learn desire. You learn to read the temperature of a room in seconds, when to perform, when to minimize, and when to disappear.
These adaptations were survival strategies that worked. But they also became muscle memory. You carry them into adulthood as relational habits: monitoring your partner's comfort level, calibrating how much space you're allowed to occupy, and accommodating hostility because you believe conflict will annihilate you.
