Watching porn is the fourth most common reason for going online. Over time, it changes and shapes sexual desires and tastes. Pornography has profound effects on the brain and in many ways affects it like a drug. Prolonged exposure can lead to addiction. Although not a specific substance, pornography produces symptoms typical of addicts. The reason is that prolonged exposure often causes long-term, sometimes lifelong, changes in the brain. Dopamine is a neurotransmitter that is released when a result is achieved. This could be food consumption, satisfaction from an effort, an event or sexual activity. Dopamine strengthens the neural connections to make us perform the same activities in the future. In other words, it changes and shapes the brain centers to cause certain actions.

When we imagine images from pornographic films during sex, the effect they have on the brain is amplified. With each orgasm, more dopamine begins to be released, which helps strengthen connections in the brain. Such an addiction can change the perception of the partner and make him seem less attractive to us.
