A depressing study in January's Journal of Sex Research found that an extraordinarily high number of people are willing to have unprotected sex - even though they have no interest in getting pregnant. It's not surprising, exactly. I know that there are millions of unintended pregnancies a year, but it's always strange to see the stats in print. In a study of almost 1500 people who were not trying to get pregnant and hadn't been sterilized, 30 percent said that they'd definitely have sex without contraception and another 20 percent said they'd be willing to do it under certain circumstances. Mind you, the fact that half of the population was unwilling to have unprotected sex was good news, but that 30 percent who didn't want a pregnancy but were also willing to throw caution to the wind? They disturb me. A lot. That's particularly true since a large proportion or study participants were at reproductive health clinics seeking out contraception. They knew its benefits. They just weren't committed to using it.
