What is the best way to prevent yourself from getting std's?

Dont have sex: That is the only dully effective method, and that includes 'traditional penile-vaginal intercourse' as well as oral and anal sex which are risky as well. Remember that over 80% of all adults over 50 years will have been infected with hpv, so its virtually universal risk. Short of abstaining, use a condow, even with oral sex, limit partners an be tested regularly.
