Arousal is responsive to what it's practised with. That much is uncontroversial — it's how conditioning works for every other stimulus too. If yours has been paired for years with a specific kind of high-novelty, high-intensity, screen-mediated input, other inputs may register as less immediate by comparison. Not because anything is damaged. Because of what's had the practice.
The reverse also works. What you can say confidently is that arousal is trainable in both directions; what nobody can tell you is how long, because that hasn't been studied.
What people report finding useful:
Reduce novelty-seeking, not just porn. Endless searching and tab-switching is a distinct behaviour from watching, and it may matter more. Some people find that stopping the search changes the experience more than stopping the content.
Slow down. Speed and intensity are habits too, and they transfer badly to partnered sex.
Attend to physical sensation over visual imagination. Practising presence in your own body, rather than running a mental highlight reel, is a skill and it transfers.
Expect a quiet stretch. Reduced interest partway through a change is commonly reported. Don't read it as damage or as evidence you need to go harder.
Don't set deadlines. "I should be fine by day 60" is a manufactured way to feel like a failure on day 61.
If difficulties persist regardless of what you do with porn, that's information too — and it points at a doctor.
Takeaways
- Conditioning, not damage. It runs in both directions.
- The search may matter more than the watching.
- A deadline is a manufactured way to feel like a failure the day after it.
Sources and how strong they are (5)
- Mixed evidencePorn-induced erectile dysfunction is a clinical hypothesis supported by case reports and clinician reports. Frequency-based population studies have not produced consistent associations, and the one longitudinal study to measure erectile function with a validated instrument over a year found that self-reported problematic use correlated with erectile difficulty at any single moment, that mere use did not, and that no pornography variable predicted the trajectory of erectile function. It remains contested.

- AnecdotalWhether tastes return to where they started after someone stops is unknown. No study has measured what a person is aroused by before, during and after a period of abstinence. What the laboratory shows is narrower and cuts both ways: arousal to one repeated sexual stimulus falls within a session, a novel stimulus restores it, and — the half usually left out of the popular version — re-presenting the original stimulus restores it too. Across sessions the evidence is weaker still. A five-man study found habituation carrying over from week to week; a 24-man study found no habituation across sessions and no change in participants' sexual behaviour outside the laboratory.

- AnecdotalWhether sexual difficulties get better after cutting down or stopping has never been tested with a controlled design. The reversal evidence everyone quotes is three clinical reports in a single 2016 paper: of those three men, one could not stop and no improvement was recorded, one improved after cutting down while simultaneously giving up a sex toy his doctor had named as a cause alongside the pornography, and one reported improvement while an inpatient being treated for a suicide attempt, alcohol use and depression. None was assessed with a validated erectile-function measure. Against that, the one longitudinal study that did use a validated measure followed men over a year and found no relationship between any pornography variable and the course of their erectile function.

- Well establishedSexual arousal habituates to a repeated erotic stimulus and recovers when a novel one is introduced. This has been shown in the laboratory across three decades, on genital response and on self-reported arousal, in men and in women, with the recovery appearing on attentional and affective measures at the same time. It is the mechanism that the endless-novelty argument about pornography rests on, and it is the reason a product that can generate the next thing on demand is acting on anticipation rather than on satisfaction - see C47, where dopamine tracks wanting rather than liking. What the mechanism does not establish is any effect specific to AI-generated content: no study has measured habituation, novelty recovery or craving for AI-generated pornography, and the one direct experimental test of the popular endless-novelty claim about internet pornography found only partial support and called for far greater nuance.
