The medical and sexological consensus — the American Urological Association ED Guideline (Burnett et al. 2018), the International Society for Sexual Medicine position, and the published sexological literature — does not identify long-term masturbation abstinence as having physiological health benefits, and does not list masturbation cessation as an evidence-based treatment for erectile dysfunction, premature ejaculation, or other sexual dysfunction. The strongest peer-reviewed evidence on the action side comes from Whelan and Brown’s 2021 cross-sectional study in the Journal of Sexual Medicine (N=942 heterosexual men aged 18-44), which found that internet pornography use alone showed no significant association with erectile dysfunction, premature ejaculation, or sexual dissatisfaction; self-perceived addiction uniquely predicted all three negative outcomes. The behaviour itself is not the regret-generating mechanism — the self-perception of problematic use is. Grubbs, Perry, Wilt and Reid’s 2019 meta-analysis (PMID 30076491) extends this finding: pornography problems are predicted more strongly by moral incongruence than by use frequency. The 10% action-side estimate is anchored on this evidence: among regular masturbators without self-perceived addiction, retrospective regret is essentially absent; the population-weighted action-side rate is the share with self-perceived problematic use multiplied by the conditional regret rate within that subgroup.
The inaction side is empirically thinner and conceptually messier. Zimmer and Imhoff’s 2020 study in Archives of Sexual Behavior (PMID 32130561, N=1,063 men recruited from a non-thematic Reddit community) found that motivation for masturbation abstinence was associated with attitudinal correlates — perception of masturbation as unhealthy, distrust in science, higher religiosity, conservative ideology — rather than with behavioural markers of hypersexuality such as maximum number of orgasms. The entry decision is predominantly belief-driven rather than behaviour-driven. Prause and Binnie’s 2024 preregistered survey of Reboot/NoFap participants in Sexualities found that increased forum engagement correlated with worse psychological outcomes including erectile dysfunction symptoms, depression, anxiety, and greater sex-negativity, and that participants reported high rates of exposure to misogynist (73.7%), anti-LGBT (42.9%), and self-harm-instructional (23.5%) content within the community. The 30% inaction-side estimate is anchored on the combination of these documented iatrogenic outcomes plus the medical-consensus position that the stated health benefits of abstinence are not supported by evidence — when the intervention does not produce its claimed benefit and carries documented psychological costs, the retrospective regret rate among participants is plausibly elevated.
The 20-point inaction-dominant delta should be held loosely on absolute magnitude and held more firmly on direction. Both rates are proxy constructions; no published survey directly asks former NoFap participants “do you regret your abstinence period?” or asks general-population adults “do you regret your masturbation frequency?” The 30% inaction-side rate is plausibly too high for the religion-motivated subgroup (where abstinence is value-aligned and the empirical claim of physiological benefit is not the load-bearing motive) and approximately correct for the health-motivated subgroup that joined NoFap expecting ED reversal or libido restoration. The 10% action-side rate is bimodal across moral-incongruence lines: near zero for non-religious occasional users, materially higher for users with strong religious or moral disapproval of the behaviour. The Reddit-derived evidence base — Zimmer and Imhoff’s 1,063 participants, Vanmali, Osadchiy, Shahinyan, Mills and Eleswarapu’s natural-language-processing analysis of r/NoFap (Archives of Sexual Behavior 2020, DOI 10.1007/s10508-020-01728-5) showing PIED-themed discussions centred on anxiety and libido, and Prause and Binnie’s preregistered iatrogenic-effects survey — over-represents young, male, Western-anglophone, internet-active participants and does not generalize to long-term abstainers for religious-observance, ascetic, low-libido, or partner-agreement reasons.
