GRAPEVINE, Texas, Jan. 13, 2012 /PRNewswire/ -- American culture often tends to associate sexuality with all that is young and glamorous, but recent studies have suggested this might be unfair. According to a brand new CNN report, the desire for sexual satisfaction is not curbed as a woman ages, and in many cases can become even more acute. CNN's medical team speculates that, for mature women as well as for mature couples, sexual pleasure could be crucial for happiness and good health. The CNN report affirms many of the teachings found in Sexperiment, a new book by prominent evangelical minister and speaker Ed Young, Jr. The CNN study suggests that mature women need regular, satisfying sex in order to be happy, a point that mirrors some of the core teachings of Ed Young's Sexperiment. In the book, the Texas pastor claims, "While many would argue, rightly so, that there is a lot more to marriage than just sex, there are also a lot of benefits." The rest of the book fleshes out these benefits, suggesting that regular sexual intimacy is a cornerstone for any happy, healthy marriage—including mature ones. CNN's report offers scientific backing to justify the points made in Ed Young's book. According to the study, there is a strong psychological connection between sexual satisfaction and overall happiness, and that, for women, this connection grows stronger with age. This finding flies in the face of the traditional view of the diminishing libido, or of sex as more appealing to newlyweds than to older couples. The study also confirms Ed Young's assessment of sex as a "tremendous catalyst" for lifelong happiness. The book Sexperiment has drawn the attention of many pastors and media personalities alike for its permissive views on sex, including Ed Young's teaching that creative and passionate sex, on a regular basis, packs big benefits for married couples. In the book, the author challenges Christian married couples to have sex every night for a week, and see how it affects their married life. CNN's study similarly suggests that, for mature women, one of the keys to happy marital life is regular sexual intimacy with her spouse.
