Psychologist and family expert Dr. Kevin Leman spoke at Christ's Church of the Valley, a non-denominational megachurch in Peoria, Arizona, on sex in marriage, as part of a series that digs into what scripture has to say about "Sex, Love & Dating."

Dr. Leman introduced himself to the congregation as a father of five and married to the same woman for 48 years, before his recent message, which was based on his book, Sheet Music.

"Sex is about the quality of your entire love life, not just the alignment of your bodies," reads the book description.

It will expand and challenge your thinking, help you start your marriage off right, or go from humdrum to exciting if you're already married."
