I bet you saw this one coming.
While most of us can watch porn without having any drop in sex drive when it comes to the real thing – watching too much porn and particularly, outrageous sexual activities that are near impossible to replicate in real-life with a partner can have a serious affect on your sex drive. This is because watching porn releases an excessive amount of dopamine which is a neurotransmitter that is responsible for initiating sexual desire and pleasure. Repeated release of significant amounts of dopamine will eventually cause you to develop a resistance to it and therefore make you “immune” to normal sexual triggers. It then becomes very hard for your brain to respond and will render you incapable of getting aroused.
If you watch a lot of porn it’s quite impractical to go cold-turkey and stop completely so you should attempt to reduce the frequency that you watch it and perhaps slowly being to change the type of porn you watch until you can get aroused something that more closely resembles a normal sexual activity between two people.
