Abstinence only education has problems

So abstinence only education works? A new study indicates that 9 of 10 in the USA had premarital sex. And we're still trying to do abstinence only sex? Frankly I'm one of the one in ten, but I suspect that is mostly due to being in denial about my sexual urges during my teen years. I didn't admit to myself the gender to whom I'm attracted and just didn't have any interest in the other gender. No matter that I was raised in a Christian home, I suspect if I'd been less in denial I'd be with those 9 out of 10.
