It's lies. Propoganda meant to scare kids out of having sex. Like back in the late 80's when they had those crazy statistics like 4,000,000 people a year were gonna be dieing of AIDS. And that everybody knows someone with AIDS.
Seriously, think about how many people fuck eachother. 80% would be like every sexually active person in the country including you, me and everybody we've ever boned. And the 20% would be little kids, the old, and the ugly. I've fucked mad bitches over the years and I aint got it. And none of them had it.
I don't know how they legally get away with these statistics.
