According to a study by Emily Rothman a professor at Boston University, published in the journal ‘Archives of Sexual Behaviour’, young adults prefer pornography as their most helpful source of information on how to have sex. The bad news is that young adults are misunderstanding the purpose of porn. Most free, online pornography is there for entertainment and to make money for the creators. The research team analysed responses from 357 young adults (18-24 years old) and 324 adolescents (14-17 years old). From a public health perspective, Rothman says it is worrisome that a sizable percentage of young adults consider porn a helpful source of information about how to have sex.
