Researchers tested young adults for spirituality, as well as other factors such as impulsiveness, traditional religious belief and attitudes toward alcohol. They found that, in women, spirituality is strongest predictor of number of sex partners, frequency of sex and tendency to engage in intercourse without a condom. However, spiritual men actually had less sex than their counterparts.
Sadly, the study provided no suggestions on the best places to meet spiritual women. So in the meantime, just assume they're in church. See you on Sunday.
