All plants and animals that reproduce sexually may develop sexually transmitted infections. They are also very common among humans. Unfortunately, many people consider sexually transmitted infection a moral issue. But the stigma and shame that result may lead people to neglect taking good care of their sexual health. Many people find it very difficult to talk about their sexual health. But discomfort and shame can get in the way of common sense. They can keep people from taking good care of themselves and their partners by practicing safer sex and getting annual sexual-health checkups with their health care providers.
