For 30 years, social science has shown that religion is good for sex: long-term couples who attend religious services regularly and say they are serious about scriptural teaching, report that they enjoy both more active and more satisfying sex lives.
But new research from Duke University shows that the connection between faith and physical intimacy can also work in the opposite direction: good sex can also strengthen belief in God. The Duke study, published in The Journal of Social Cognitive and Affective Neuroscience, focuses on oxytocin, a hormone generally produced during physical intimacy. For men in particular, higher levels of oxytocin mean greatly enhanced spiritual sensibility, and a greater sense of wholeness and well-being.
In other words, strong faith and good sex can encourage one another in a virtuous cycle, indicating that those who search for partners at worship services and other religious settings may, in fact, be looking in the right place.
