Touch, outside of sex

When couples describe what they miss most in a struggling relationship, the answer is more often ordinary physical affection than sex, and the two are more connected than either party usually realises.

What touch does

The physiology is reasonably well characterised.

Gentle stroking at a particular speed activates a specific class of nerve fibres associated with pleasant social touch, which project to brain regions involved in emotion rather than to those handling discriminative sensation.

Touch is associated with oxytocin release, reduced cortisol and reduced sympathetic activation in laboratory studies.

Hand-holding during a painful or threatening stimulus reduces reported distress and alters neural threat responses, with the effect being larger with a partner than a stranger.

Effects on blood pressure and heart rate have been demonstrated in controlled conditions, though the magnitudes are modest and the literature has the replication problems common to this area.

Why it disappears

The pattern that couples describe repeatedly.

When sex has become fraught, the lower-desire partner begins avoiding touch that might be interpreted as initiation, in order to avoid the negotiation.

The higher-desire partner, receiving less touch, initiates more, which increases the avoidance.

Within months there is essentially no physical contact of any kind, which removes the ordinary connection that made the relationship feel close and makes sex less likely still.

This is one of the most common and most reversible patterns in psychosexual practice.

Breaking it

Requires an explicit agreement, which sounds unromantic and works.

The standard clinical approach involves an agreed period in which certain activities are off the table entirely, so that touch carries no risk of escalation.

What this does is remove the ambiguity: the avoidant partner can relax into affection because they know where it is going, and the other can offer it without it being a bid.

Paradoxically, the removal of pressure frequently restores desire, which is why the approach exists.

The version couples can do without a therapist is simpler: agree what is currently allowed and what is not, and stick to it.

The other kinds of touch

Worth naming, since affection has become narrow in many relationships.

Hugging on arrival and departure.

Hand-holding.

Sitting in contact rather than at opposite ends of a sofa.

A hand on the shoulder in passing.

Massage, without expectation.

Sleeping in contact, or not, according to what each person actually wants rather than what has become habitual.

And touch during conflict, which is difficult and which some couples find defuses arguments considerably.

Touch deprivation

A real phenomenon with a growing literature.

People living alone, older people, those who are bereaved, and those who are isolated may go long periods with no physical contact at all.

Studies during periods of enforced isolation found associations between reduced touch and higher anxiety and lower wellbeing.

The alternatives available — massage, physical activities involving contact, animals, and simply asking friends and family for hugs — are partial and are better than nothing.

Pets specifically have a reasonable literature on physiological effects of contact.

Differences in what people want

Which cause as much difficulty as differences in sexual desire and are discussed far less.

People differ substantially in how much touch they want, how they like to receive it, and how tolerable it is when they are stressed or overstimulated.

Sensory sensitivity is a genuine factor for some people, and touch aversion is common in autistic adults and in those with sensory processing differences.

Touch saturation is real for parents of small children and for carers, and being touched all day by a dependent person genuinely reduces capacity for it in the evening.

And a history of trauma changes what touch means, sometimes unpredictably.

All of which argues for asking rather than assuming, and for treating a preference as information rather than as rejection.

The practical suggestion

For couples where this has eroded.

Reintroduce one specific, small, daily instance — a hug of a defined length, or sitting in contact for the length of an episode of something.

Make it explicitly non-sexual by agreement.

Do it for a few weeks before drawing conclusions.

And notice that this is generally easier to start than a conversation about sex, and frequently makes that conversation possible.
