how important is sex in a marriage

February 24, 2026

Sex is usually quite important in a marriage, but how important depends a lot on the couple, their values, and their physical and emotional needs. Many long-term couples describe sex not just as “a bonus,” but as one of the main ways they feel loved, chosen, and emotionally connected.

What “important” really means

Sex tends to support emotional intimacy by releasing bonding hormones like oxytocin, which can increase feelings of closeness, trust, and warmth between partners.

Research and clinical experience suggest that when sex is mutually desired and satisfying, it often boosts overall relationship satisfaction for at least a couple of days afterward (“afterglow” effect).

For many couples, a lack of sex is less about the physical act and more about feeling rejected, undesired, or disconnected, which can slowly erode the relationship if never talked about.

It’s not one-size-fits-all

There is no “right” frequency; some happy couples have sex several times a week, others a few times a month, and some prioritize other forms of affection like cuddling or talking in depth.

Mismatched libidos are extremely common, especially with stress, kids, aging, health issues, or medication, so what worked in your 20s might not fit your 30s or 40s.

Asexual or low-libido partners can still have strong marriages if there is honest communication, negotiated expectations, and other reliable ways to feel loved and secure.

When lack of sex becomes a problem

A long-term, unspoken shutdown of sexual or physical intimacy often shows up alongside growing resentment, more conflict, or a “roommate” feeling.

Many people in forum discussions say that what hurts most is not the low frequency itself, but feeling ignored when they try to talk about it or being shamed for having needs.

On the other side, some feel pressured to perform or provide sex as an obligation, which can make sex feel unsafe or transactional, and that also damages the bond.

How to talk about it with a spouse

Use “I” statements about your feelings and needs instead of blame, such as “I miss feeling close to you” or “I’d like us to talk about our sex life and what feels good for both of us.”

Bring in the bigger picture: talk about stress, energy, health, body image, or unresolved conflicts that might be dampening desire instead of focusing only on frequency.

If conversations get stuck or turn into fights, many couples benefit from couples therapy or sex therapy to have a safer, guided space to negotiate what works for both.

Quick bottom line

Sex is not the only ingredient in a good marriage, but for many people it is a major channel of affection, reassurance, and emotional connection.

A marriage can survive or even thrive with less sex if there is clear communication, shared expectations, and other strong forms of intimacy; it usually struggles when silence and hurt build up around the topic.
