I don't know any young man or woman who knows better. Knowing better is emotional security and a grounded self-confidence not obsessively oriented towards sexuality. Mature young adults make commitments and handle responsibilities--hence marriage or long-term relationships. Besides, sister, this is not an argument between traditionalism vs. liberalism. Ideology has no place in the bedroom.
Further, the figure of 50% is a rough estimate that is most likely inaccurate for the simple fact that there is no real test for HPV. Doctors in the clinics will actually tell you--and this figure I know word of mouth from my fiance
(from a medical doctor!)--that the figure is the 80%. Women have to get pap smears to test for cancerous cells that are effects of the HPV, but there is no actual clinical test to find the over one hundred and thirty strains of the virus. In men it is undetectable, except in very rare occasions where males erupt in genital warts (estimated 10-15 strains of HPV cause genital warts). So, the argument that promiscuous teenage sex is okay is medically an unsound opinion, because
even using contraception YOU CAN STILL RECEIVE HPV--and the Gardasil is physiologically and psychologically damaging young women (now they want to give it to little boys too), including death in many cases.
