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