How does sexual conditioning work? The short answer is sensitization. Sensitization occurs when the brain wires together the sights, sounds, smells, sensations, emotions, and memories associated with a big reward, such as climax – creating a pathway that can trigger the brain’s reward system in the future. When activated by these triggers (cues), this pathway creates powerful, hard to ignore, urges. These items reveal some of the neurochemical mechanisms involved.
