What happens when you drop a male rat into a cage with a receptive female rat? First, you see a frenzy of copulation. Then, progressively, the male tires of that particular female. Even if she wants more, he has had enough. However, replace the original female with a fresh one, and the male immediately revives and gallantly struggles to fertilize her. You can repeat this process with fresh females until he is completely wiped out.

This is called the Coolidge effect—the automatic response to novel mates. Interestingly, men ejaculate more motile sperm and they do it more quickly when they view a novel porn star. This powerful automatic response to erotic novelty is what started you down the road to getting hooked on internet porn.

Studies linking porn use or porn/sex addiction to sexual dysfunctions, lower arousal, and lower sexual & relationship satisfaction

Reality Check - Regardless of what you may read in some journalistic accounts, multiple studies reveal a link between porn use and sexual performance problems, relationship and sexual dissatisfaction, and reduced brain activation to sexual stimuli.

Let's start with sexual dysfunctions. Studies assessing young male sexuality since 2010 report historic levels of sexual dysfunctions, and startling rates of a new scourge: low libido. Documented in this lay article and in this literature review by the US Navy.

Brain Studies on Porn Users

This page lists all the studies assessing the brain structure and functioning of Internet porn users. To date every study offers support for the porn addiction model (no studies falsify the porn addiction model). The results of these 33 neurological studies (and upcoming studies) are consistent with 210+ Internet addiction "brain studies", many of which also include internet porn use. All support the premise that internet porn use can cause addiction-related brain changes, as do 12 recent neuroscience-based reviews of the literature:

What about Virtual Reality (VR) porn?

A 2017 paper by VR porn researchers reports that,

We found that for most people the potential of a VR porn experience opened the doors to an apparently 'perfect' sexual experience - a scenario which in the real world no-one could live up to. For others it meant pushing the boundaries, often with highly explicit and violent imagery, and we know from current research into pornography that exposure to this content has the potential to become  addictive and more extreme over time.
