Some say talking about abstinence as a means of prevention leaves out the teens who may be having or have had sex, already. Others say having a conversation that focuses solely on condom use leaves out the kids who may not be having sex.

But are we selling our teens short by thinking that just because they've had sex in the past that they'll want to continue to have sex? Or that if the teens not having sex knew how not to get HIV and STDs then that would encourage them to begin having sex?
