The most common STD in this country is human papillomavirus or HPV, but most men aren't vaccinated against the disease.
A new study of nearly 2,000 men revealed nearly half of them had contracted the virus, but only 10-percent had been vaccinated.
Men between 18 and 22 had the lowest rates of HPV infection.
Researchers say this is most likely due to the current standard of giving the vaccine to younger males.
