February in [email protected]

It’s February, and February means Valentine’s Day. And for many people, Valentine’s Day means love, chocolates, flowers and…sex. So our focus this month is sexuality and sexual behavior. For sexual and reproductive health researchers, the study of sexuality and sexual behavior often comes down to the numbers that inform the need for or effectiveness of interventions—the age at which people begin having sex, the frequency with which sexual activity occurs, how people’s sexual behavior changes (or doesn’t) when they learn about risks of unwelcome outcomes and so on. But it’s also important to know how people think about sex (just what is sex, anyway?) and what it means to them in the context of their lives and relationships; articles in Perspectives have covered that, too. Stay with us as we revisit how these topics have been treated over the past decades.
