If you read the blog post about serial killers and
pornography, you probably noticed that there is an escalating factor associated
with pornography use. Distributors of
pornography cash in on this phenomenon because they know that as people become
addicted to pornography they often keep wanting more and more. So even though there is a lot of free
pornography out there, addicts will begin to pay for more intense types of
pornography to help try to satisfy the need.
Our brains have a reward center with “liking” and “wanting”
systems that are impacted by pornography usage.
The Liking system provides the pleasurable feelings you experience when
it is activated. The chemical CREB is
released and causes the pleasurable feelings to fade and leave the person
satisfied. If too much of the CREB
chemical is released from engaging in addicted behaviors like using drugs and pornography, CREB
will build up and the pleasure response becomes blocked. The addicted person will find less enjoyment
from their usage, so they will need more to feel a “high”.
The Wanting system uses the protein called DeltaFosB to rewire itself as a response to intensely pleasurable experiences. This forms new brain connections, so the
experiences are remembered and the desire to repeat the pleasurable experience
becomes part of the brain wiring.
The Wanting and Liking systems cause the user to want more
and more even though they like it less and less, leading to the escalating use
of pornography. For more information, see
