Do atheists have better sex? Yes. According to science, that is -- and more specifically, according to the recently released "Sex and Secularism" study.
In January 2011, organizational psychologist Darrel Ray, Ed.D. (psychologist for 30 years and author ofThe God Virus as well as two books on psychology) and Amanda Brown (undergraduate at Kansas University, focused on sexuality and sex therapy) conducted a sex survey of over 14,500 people -- atheists, agnostics, and other people in the secular community. The survey was looking at religion, atheism, and sex: how religion affects sex, how leaving religion affects sex, whether lifelong atheists feel differently about sex than people who have recently deconverted, and so on. The report -- "Sex and Secularism: What Happens When You Leave Religion?" -- is on the Internet, and if you want all 46 pages of the naughty details, including the charts and graphs and personal stories, you can download it free (you just need to register on the site).
But if you just want to know the gist?
Leaving religion improves people's sex lives.
