Sexual frequency and satisfaction: the data

How often people actually have sex

Large representative surveys give a consistent picture, and it is lower than most people assume.

• Natsal-3 (Mercer et al., 2013, Lancet), surveying 15,162 adults in Britain, found a median of three occasions of sex in the past four weeks among 16–44 year olds — down from five in Natsal-1 (1990–91) and four in Natsal-2 (1999–2001).
• US General Social Survey analyses (Twenge et al., 2017) found American adults had sex roughly nine fewer times per year in the early 2010s than in the late 1990s, with the decline concentrated among partnered people rather than single people.
• Declines have been documented across Britain, the US, Australia, Japan, Finland and Germany over the same period.

Proposed explanations include longer working hours, smartphone and streaming displacement of bedtime, rising rates of mental health difficulty and psychotropic medication use, more people living alone for longer, and — a positive interpretation with some support — reduced unwanted or obligated sex as expectations of consent have shifted.

Frequency and wellbeing

Muise, Schimmack and Impett (2016, Social Psychological and Personality Science), analysing three studies including over 30,000 people, found that higher sexual frequency was associated with greater wellbeing in people in relationships — but the association levelled off above about once a week. More than weekly was not associated with further gains.

The same research programme found no association between frequency and wellbeing for single people, indicating the effect is about relationship quality rather than sex itself.

Loewenstein et al. (2015) ran the relevant experiment: couples randomly assigned to double their sexual frequency for three months reported slightly lower happiness and sexual enjoyment than controls. Instructed frequency is not the same thing as wanted frequency, which is precisely the finding.

What actually predicts satisfaction

Frequency is a weak predictor. The consistently stronger ones:

• Sexual communication. Mallory et al.'s meta-analysis (2019) of 93 studies found significant associations with both sexual satisfaction (r ≈ 0.35) and relationship satisfaction (r ≈ 0.37).
• Relationship satisfaction generally, which is bidirectionally related to sexual satisfaction over time.
• Behavioural variety. Frederick et al. (2018) found orgasm rates highest in encounters including oral sex, manual stimulation and deep kissing, not in those with the longest intercourse.
• Feeling desired, and mutual initiation rather than one-sided.
• Sexual growth beliefs — the belief that good sex is built through effort — predict better outcomes over time than sexual destiny beliefs, the belief that good sex reflects innate compatibility (Maxwell et al., 2017).
• Equity in domestic labour, repeatedly associated with higher frequency and satisfaction in the partner carrying more.

Comparison is the problem

Overestimating others' frequency is well documented and is itself associated with lower satisfaction. Most people's benchmark comes from fiction, pornography and boasting, none of which sample the population.

Two implications follow. First, "less than average" is not meaningful when the average includes enormous variation and the distribution is skewed. Second, the useful question is not how you compare, but whether both people are content — a couple having sex monthly and happy about it is doing better than a couple having sex weekly and unhappy about it.

Dead bedrooms and the low end

Some couples have no sex at all. Where both are content, this is not a problem requiring intervention; asexual and low-desire partnerships can be entirely satisfying. Where one is not content, it is worth addressing early, and the strongest predictor of it becoming intractable is how long it goes unaddressed.

The most effective known interventions are behavioural and relational rather than pharmacological: sensate focus, scheduling, addressing the load, treating medication effects, and sex therapy.
