Causes of Sexless Marriage and How to Address It - The Reality of Japanese Couples and Paths to Resolution

The Reality of Sexlessness in Japan

According to surveys by the Japan Family Planning Association, approximately 47% of married couples have not had sexual intercourse for over a month, meeting the definition of "sexless." This figure has been trending upward year after year and is exceptionally high by international standards.

Sexlessness is not merely a "frequency issue." The lack of physical intimacy ripples through the entire relationship - emotional disconnection, declining self-esteem, distrust toward one's partner, and increasing loneliness. However, some couples are mutually satisfied despite being sexless, so it cannot be universally labeled as a problem. It becomes problematic when one or both partners are suffering from the situation.

Psychological Causes

One of the most common psychological causes is the "family-ization" of the marital relationship. After having children, many couples shift entirely into parent roles, and the romantic and sexual dimensions of their relationship fade into the background. Particularly in Japan, where the cultural norm of "mother" carries strong desexualization, many women report difficulty switching between maternal and sexual identities.

Performance anxiety is another significant factor. For men, anxiety about erectile function or premature ejaculation can create avoidance patterns. For women, pain during intercourse (dyspareunia) or difficulty reaching orgasm can make sex feel like an obligation rather than pleasure. Once negative associations form, the avoidance cycle self-reinforces.

Past trauma, including sexual abuse or assault, can also manifest as sexual avoidance within marriage. These cases require professional support rather than simple communication strategies.

Physical Causes

Chronic fatigue from overwork is frequently cited as a cause, but it often serves as a socially acceptable excuse masking deeper issues. True physical causes include hormonal changes (testosterone decline in men, estrogen fluctuation in women), medication side effects (antidepressants, blood pressure medications), chronic pain conditions, and sleep disorders.

For women, postpartum hormonal changes, breastfeeding-related vaginal dryness, and pelvic floor dysfunction can make intercourse physically uncomfortable. These are medical issues with solutions, but many women suffer in silence due to embarrassment or lack of information.

Age-related changes affect both partners. Declining testosterone in men after 40 reduces spontaneous desire, while menopausal changes in women can alter arousal patterns. Understanding these biological realities helps couples adapt rather than blame.

Relational Causes

Unresolved conflicts, accumulated resentment, and emotional disconnection are powerful inhibitors of sexual desire. When daily communication breaks down, physical intimacy becomes nearly impossible. Many sexless couples report that the bedroom issue is merely the most visible symptom of broader relational problems.

Power imbalances also contribute. When one partner consistently controls decisions, finances, or household management, the other may unconsciously withdraw sexually as the only domain where they retain autonomy. (Books on rebuilding marital intimacy can offer guidance here.)

The pursuer-distancer dynamic is particularly common: one partner initiates and gets rejected, eventually stops trying, and both settle into a sexless pattern that neither actively chose. Breaking this cycle requires both partners to acknowledge their role in maintaining it.

Starting the Conversation

The first step toward addressing sexlessness is honest dialogue, which is often the hardest part. Choose a neutral time (not in bed, not during conflict) and use "I" statements: "I miss feeling close to you" rather than "You never want to have sex."

Acknowledge that the conversation itself may feel uncomfortable. Normalize the difficulty: "I know this is awkward to talk about, but our connection matters to me." Listen to your partner's perspective without defensiveness. They may reveal fears, physical discomfort, or emotional needs you were unaware of.

For couples who find direct conversation too difficult, coping with a sexless relationship offers alternative approaches. Some couples benefit from writing letters, working with a couples therapist, or starting with non-sexual physical affection to rebuild comfort with touch.

Rebuilding Physical Intimacy

Rebuilding intimacy after a long sexless period requires patience and graduated steps. Sensate focus exercises, developed by Masters and Johnson, involve structured touching without the pressure of intercourse. This removes performance anxiety and allows both partners to rediscover pleasure in physical connection.

Scheduling intimacy may sound unromantic, but for busy couples, it signals mutual prioritization. The goal is not mechanical obligation but creating protected time for connection. What happens during that time can range from massage to conversation to sex - the commitment is to showing up.

When Professional Help Is Needed

If self-help approaches haven't improved the situation after 3-6 months of genuine effort, professional support is recommended. Sex therapists, couples counselors, and in some cases medical professionals can address issues that couples cannot resolve alone.

Seeking help is not a sign of failure - it is a sign that the relationship matters enough to invest in. Many couples report that therapy helped them understand patterns they could never have identified independently.
