The brain has been trained to find the screen (novelty) arousing and the physical partner (familiarity) boring.
In evolutionary terms, dopamine was designed to keep us alive. When our ancestors saw a ripe berry, a spike of dopamine said, "Seek it. Get it. Now." When they mated, dopamine ensured they would try again. The brain is hardwired to seek novelty and reward.
As tolerance builds, many users report a shift toward genres they never would have considered initially—more aggressive, niche, or taboo content. Neurobiologically, this is the brain’s attempt to find a novel stimulus strong enough to punch through the now-numbed reward circuitry. Escalation does not imply a change in underlying sexual orientation; it implies a change in the brain’s sensitivity to dopamine.
