For most American youth and young adults, thanks to the relentless messaging of popular and mass culture, sex is indeed everywhere. This is true not only in the imaginative world of media but also in their actual experience, in relationships unsupervised by adults or extended family. Especially among young adults, but even among many middle schoolers and high schoolers, the easy-everywhereness of sex is dramatically increased by easy-everywhere access to alcohol, cannabis, or other drugs.
