I'll just leave this right here: http://www.washingtonpost.com/news/book-party/wp/2015/03/12/she-took-a-year-off-from-her-marriage-to-sleep-with-strangers-what-could-go-wrong/

Quote from the Washington Post article: “The Wild Oats Project” is the year-long tale of how a self-described “good girl” in her early 40s moves out, posts a personal ad “seeking single men age 35-50 to help me explore my sexuality,” sleeps with roughly a dozen friends and strangers, and joins a sex commune, all from Monday to Friday, only to rejoin Scott on weekends so they can, you know, work on their marriage.

TL:DR: A woman in her early 40's wants to have children, and her stoic husband doesn't. So she goes on a year-long quest of sleeping with multiple single men, to 'explore her sexuality'. All this with her husband's approval. She then writes a book about her experience.
