At a glance

  • Intimacy can be emotional, physical, intellectual or experiential, and it does not have to involve sex.
  • Psychologists see it as a process that builds through repeated moments of sharing and caring responses.
  • Friends, family members and partners can all share intimacy.
  • A sexual relationship can exist with little intimacy, and deep intimacy can exist without sex.

In detail

Psychologists usually describe intimacy as something that grows over time through repeated moments of openness and responsiveness. One person shares something that matters to them, the other responds with understanding, and trust gradually deepens. Researchers such as Reis and Shaver framed this as an interpersonal process rather than a fixed trait.

People often use the word as a polite synonym for sex, but the broader meaning is more useful. Friends, family members and partners can all share intimacy, and a sexual relationship can exist with very little of it. Many people find that emotional and physical closeness reinforce each other when both are present.

In a sentence

  • We've been together for years, but lately the intimacy feels like it's been replaced by logistics.
  • For me, intimacy is staying up late talking, not just being physically close.

Where the word comes from

The word comes from the Latin intimus, meaning innermost. It entered English in the 17th century, describing close familiarity, and was later also used as a polite euphemism for sex.

Not to be confused with

  • Sex

    Sex can be part of intimacy, but intimacy describes closeness and being known, which can exist without any sexual contact.

Common questions

Does intimacy always mean sex?

No. People often use the word as a polite way of referring to sex, but in psychology it means closeness built through being known, accepted and cared for. It can be emotional, intellectual or shared through experiences, and many intimate relationships, such as close friendships, are not sexual at all.

How does intimacy grow?

Researchers describe it as growing step by step: one person shares something that matters to them, the other responds with understanding, and trust gradually deepens. Small everyday moments of openness and responsiveness tend to matter as much as big conversations.
