I read in an Atlantic piece that there was a "sex recession" [1] - many sociological studies show that people are having less sex than decades prior. It's counter-intuitive, but the data in the article meets my anecdotal observation (and I don't even live in the US). Assuming both articles are somewhat accurate the correlation would pull in opposite directions.
