A sexless marriage is a term used to describe a marital relationship in which there is little or no sexual activity between the partners. This can be due to various reasons such as health issues, emotional barriers, lack of attraction, or simply a decrease in interest over time. While some couples may choose to have a sexless marriage by mutual agreement, others may experience it unwillingly and feel unhappy about it. A sexless marriage can put strain on the relationship and lead to feelings of isolation, loneliness, and even depression for one or both partners.
