A sexless marriage is typically defined as a marital relationship in which the partners engage in sexual activity infrequently or not at all. While the exact frequency can vary, many experts suggest that a marriage may be considered sexless if the couple has sexual relations less than 10 times a year.

There are several factors that can contribute to a sexless marriage, including:
Physical Health Issues: Medical conditions such as hormonal imbalances, chronic illnesses, or disabilities can significantly impact a person's libido. For example, a partner suffering from diabetes may experience erectile dysfunction, which can hinder sexual activity.
Emotional and Psychological Factors: Stress, anxiety, depression, and unresolved conflicts can lead to a decrease in sexual desire. For instance, a couple going through financial difficulties might find that their emotional strain affects their intimacy.
Life Stages and Responsibilities: Different life stages, such as having young children or caring for elderly parents, can shift priorities and reduce the time and energy available for intimacy. Couples may find themselves too exhausted to engage in sexual activity after a long day of work and childcare.
Relationship Dynamics: A lack of communication, emotional disconnection, or unresolved issues can create a rift between partners, leading to decreased sexual activity. For example, if one partner feels unappreciated or neglected, they may withdraw from sexual intimacy.
Changes in Desire: It is natural for sexual desire to fluctuate over time. Couples may experience periods where one or both partners have a significantly lower libido, which can contribute to a sexless marriage.

For example, consider a couple, John and Lisa, who have been married for over 15 years. In the early years, they had a fulfilling sexual relationship, but as they welcomed children and both took on demanding jobs, their sexual encounters dwindled. After a few years, they found themselves in a situation where they had not had sex in over a year. Despite their love for each other, the pressures of life and lack of communication about their needs led to a sexless marriage.

Another example could involve a couple, Mark and Sarah, where Sarah experienced postpartum depression after the birth of their child. Mark, wanting to support Sarah, prioritized her emotional well-being over their sexual relationship. As a result, intimacy became a secondary concern, leading to a prolonged period without sexual activity.

It's important to recognize that a sexless marriage can have emotional and psychological repercussions for both partners. Feelings of rejection, frustration, and inadequacy may arise, potentially leading to infidelity or separation if the issues are not addressed. Communication and seeking professional help, such as couples therapy, can be vital in navigating these challenges.

Ultimately, what constitutes a sexless marriage can vary from couple to couple, and it is essential for partners to discuss their needs and expectations openly. Understanding and addressing the underlying issues can help revive intimacy and strengthen the marital bond.
