A sex therapist says sexual desire and frequency can naturally change during marriage, particularly with ageing and major life events. She warns that treating a decline in desire as inherently abnormal can leave couples feeling disconnected, while open communication about intimacy is more important than meeting a presumed standard.

Dr Anna Elton, a Massachusetts-based marriage and family therapist and clinical sexologist, says there is no medically prescribed number of sexual encounters that defines a healthy sex life. Research suggests lifestyle and relationship factors can affect libido, but couples should focus on agreeing a routine that feels comfortable for both partners and addressing unmet needs honestly.
