Another study by the Kinsey Institute sampled 484 people, ranging in ages 18–96.The study reported that nearly 95% of its participants "agreed that penile–vaginal intercourse meant 'had sex.' But the numbers changed as the questions got more specific".The Centers for Disease Control and Prevention (CDC) stated in 2009 that "although there are only limited national data about how often adolescents engage in oral sex, some data suggest that many adolescents who engage in oral sex do not consider it to be 'sex'; therefore they may use oral sex as an option to experience sex while still, in their minds, remaining abstinent".The specificity of questions concerning sexual activity can additionally affect definitions of sexual intercourse or other sexual behaviors.

Religious views on sexuality vary significantly between different religions and sects of the same religion, though there are common themes, such as prohibition of adultery.
A 1999 study by the Kinsey Institute examined the definition of sex based on a 1991 random sample of 599 college students from 29 U. states; it reported that while "virtually every college student they surveyed considered penile–vaginal intercourse to be sex," and 19–20% said that anal intercourse was not sex, 60% said oral-genital contact (fellatio, cunnilingus) did not constitute having sex.
