Safe sex is good sex.
According to the National Institute of Allergy and Infectious Diseases, STDs are among the most common infectious diseases in the U.S., affecting more than 13 million men and women each year. STDs often don't have symptoms, so an infection can fester or spread and lead to complications, especially in women. If you think you have contracted an STD, you should see your doctor right away to get tested, especially because you may pass it on to another person without realizing it. Nearly two-thirds of STDs occur in people 25 and younger. The rate of STDs is rising, in large part because more people are sexually active at an earlier age.
