Key takeaways

  • The physical-or-psychological question is the wrong one. Almost every persistent difficulty has a physical component and a psychological one maintaining it, and treating only one half is why so many attempts fail.
  • Anxiety about performance is the most common maintaining factor. Attention shifts from sensation to self-monitoring, which suppresses the physical response, which confirms the fear, which is a loop that runs regardless of what started it.
  • Medication is a frequent and under-recognised cause. Several very widely prescribed drug classes affect sexual function, and people often stop treatment rather than mention it.
  • Low desire is not a single thing. Desire that was never high, desire that disappeared, and desire that exists but not for this partner are three different problems with three different answers.
  • Erectile difficulty can be an early cardiovascular sign. The vessels involved are small and are affected first, so a new, gradual-onset difficulty is a reason to see a doctor about more than sex.

Sexual difficulties are common, are usually treatable, and are routinely approached through the one question that guarantees the wrong answer: is this physical or psychological. Almost every persistent problem has a physical contributor and a psychological one keeping it going, and the half that is ignored is the half that brings it back. [mccabe-2016-definitions] This guide covers what these difficulties are, what causes and sustains them, and what treatment actually works.

What counts, and what does not

A sexual difficulty becomes a clinical problem when it is persistent, present on most occasions over roughly six months, and causing distress.

Both halves matter. Occasional difficulty is nearly universal and is not a condition. And a level of sexual interest that is low by some external standard but bothers nobody involved is not a disorder either, which is a genuinely important guard against pathologising ordinary variation.

The main categories are difficulties with desire, with arousal, with orgasm, and pain during sex. They overlap heavily in practice, and it is common for one to produce another.

What tends to be maintaining a persistent difficulty Illustrative
Both not either
  • Anxiety and self-monitoring 40% of maintaining factors
  • Medical or medication factors 30% of maintaining factors
  • Relationship context 20% of maintaining factors
  • Other contributors 10% of maintaining factors

The multifactorial picture described in the Fourth International Consultation on Sexual Medicine consensus (McCabe and colleagues, 2016). Values illustrate the point that maintaining factors are mixed rather than reporting measured proportions.

The loop that keeps it going

Whatever starts a difficulty, one mechanism sustains most of them.

A difficulty occurs, for any reason: alcohol, tiredness, a new medication, stress, a difficult conversation earlier that evening. On the next occasion there is now something to worry about. Attention shifts from sensation to monitoring, checking whether it is working. That shift is itself enough to suppress the physical response, because arousal depends on attention being somewhere other than on assessing arousal.

The failure then confirms the fear, and the loop is closed. It runs perfectly well after the original cause has disappeared entirely, which is why “the medication was changed months ago and it did not help” is such a common report.

Breaking it involves moving attention back to sensation and removing the performance frame, which is what most of the effective psychological treatment consists of.

Medical and medication causes

ContributorWhat it typically affects
SSRI antidepressantsDesire, and delayed or absent orgasm
Some blood pressure medicationsErectile function, arousal
Hormonal changesDesire, arousal, comfort
Diabetes and vascular diseaseErectile function, arousal, sensation
Thyroid disordersDesire, energy, arousal
Alcohol, regularlyArousal and orgasm, in both the short and long term
Depression and anxiety themselvesDesire above all, independently of any medication

The medication row is the one most often left unspoken. Montejo and colleagues describe the substantial impact of psychotropic medication on sexual function and the clinical importance of asking about it, since people frequently stop effective treatment rather than raise the side effect. [montejo-2019-ssri] Options usually exist, including dose changes, timing and switching, but only if the subject is opened.

The row worth taking seriously for a different reason is vascular. Gandaglia and colleagues reviewed the association between erectile dysfunction and cardiovascular disease, and the direction of the finding is that erectile difficulty can precede a cardiac event by years, because the vessels involved are small and narrow first. [gandaglia-2014-cardio] A new, gradual-onset erectile difficulty is therefore a reason to have blood pressure, cholesterol and glucose checked, whatever else is done about it.

Low desire is three different problems

Grouping them together is why so much advice about desire lands as useless.

Desire that was never high. A long-standing baseline, with no change and no obvious cause. Distress here usually comes from comparison with an expectation rather than from a loss, and the useful conversation is often about the expectation.

Desire that disappeared. A change from a previous baseline. This is the one that most warrants a medical look, because it is the pattern produced by medication, hormonal change, thyroid problems, depression and chronic fatigue.

Desire that exists but not here. Present in other contexts, absent in this relationship. No medical investigation will find anything, because there is nothing medical to find, and the answer lies in the relationship rather than the body. Our guide to relationships covers that territory.

Distinguishing between the three takes one question about timing and one about context, and it changes the whole approach.

What treatment works

Psychological treatment has good evidence. Frühauf and colleagues pooled trials of psychological interventions across sexual difficulties and found meaningful improvement in symptom severity and satisfaction. [fruhauf-2013-psychological]

The common ingredients are consistent: reducing the performance frame, deliberately shifting attention back to sensation rather than assessment, graded exercises that begin without any expectation of intercourse, addressing beliefs about what sex is supposed to look like, and involving the partner where there is one, since a difficulty in a couple is rarely a problem located in a single person.

Medical treatment sits alongside rather than instead: treating an underlying condition, adjusting a medication, and drug treatments where appropriate. The combination outperforms either alone for most persistent difficulties, which follows directly from the fact that most persistent difficulties have both kinds of cause.

Where anxiety is the dominant maintaining factor, our guide to anxiety covers the mechanism in general, and the anxiety screener may be worth ten minutes.

When to seek help

See a doctor if a difficulty has lasted several months, if it began after starting or changing a medication, if there is pain, or if erectile difficulty came on gradually and has worsened, which warrants a cardiovascular check regardless of what is done about the sexual symptom. Raise it even if it feels too minor to mention, since the alternative is often years of avoidance over a problem with a straightforward answer.

If you are in crisis, contact your local emergency services or a crisis helpline.

Frequently asked questions

What counts as sexual dysfunction?

A persistent difficulty with desire, arousal, orgasm or pain during sex that causes distress to the person experiencing it. The distress criterion is doing real work in that definition: a low level of interest in sex that bothers nobody is not a disorder, and the same level accompanied by distress is worth addressing. Duration matters too. Occasional difficulty is close to universal and is not a condition. The threshold most clinicians use is a problem present for most occasions over roughly six months.

Is sexual dysfunction physical or psychological?

Nearly always both, and the question itself is what obstructs treatment. A physical factor commonly starts a difficulty and a psychological factor commonly maintains it. A single episode caused by alcohol, tiredness or a medication can produce anxiety about the next occasion, and that anxiety alone is enough to keep the problem going after the original cause has gone. This is why treating only the physical side often produces temporary improvement, and why treating only the psychological side fails when there is an untreated medical contributor underneath.

Can medication cause sexual problems?

Yes, and it is one of the most common causes and one of the least often raised. Selective serotonin reuptake inhibitors, widely prescribed for depression and anxiety, frequently affect desire and delay or prevent orgasm. Several blood pressure medications, some antipsychotics, hormonal contraception and finasteride are also implicated. This matters because people frequently stop an effective medication rather than mention a side effect they find embarrassing. There are usually options, including dose adjustment, timing changes and switching, so raising it is worth the awkward minute.

What causes low sexual desire?

Low desire has more possible causes than any other sexual difficulty, which is why a single explanation is rarely right. Physical contributors include hormonal changes, thyroid problems, chronic pain, fatigue and medication. Psychological contributors include depression, anxiety and stress. Relational contributors include unresolved conflict, loss of emotional closeness, and mismatched expectations. And there is the category people are most reluctant to name, which is that desire is present but not for this relationship in its current form. Distinguishing between never had much, used to and no longer, and yes but not here is the first useful step.

When should I see a doctor about a sexual problem?

See a doctor if a difficulty has persisted for several months, if it began after starting a medication, if there is pain, or if it appeared gradually and has worsened, particularly with erectile difficulty, which can be an early sign of cardiovascular disease because the blood vessels involved are among the smallest and are affected first. Also worth seeing someone if the difficulty is causing significant distress or affecting a relationship, regardless of how long it has been going on. Sexual difficulties are ordinary clinical territory and do not need to reach a threshold of seriousness before being raised.
