For many, the word intimacy is often associated with sex or physical connection. While the two things are forms of intimacy, the word itself can be used in many different situations.
Merriam-Webster defines the word intimate as marked by a warm friendship developing through long association. This reminds us that intimacy develops over time. An intimate connection with your spouse is essential to marriage, but it takes intentionality and the willingness to commit to developing that part of your relationship.
