The following methods are proven to reduce the risk of contracting STDs: Practice Abstinence — The only way to completely avoid contracting an STD is to not have sex, including vaginal, oral, or anal sex. Use Condoms — The most popular form of STD prevention is using a condom, which when used correctly every time, can significantly reduce the risk of contraction. Certain STDs, like herpes, can be transmitted via skin to skin contact and are not always preventable with condom use alone. Have Fewer Partners — Limiting sexual partners also lowers the chance of contracting an STD, especially if the relationship is monogamous. Receiving a test to ensure both parties are STD-free is one of the most reliable ways to avoid STDs. Get Vaccinated — Many common STDs can be prevented by a vaccine, such as HPV (human papillomavirus). These vaccines are safe, effective, and can help avoid health problems. Get Tested — Many STDs do not exhibit symptoms, however they can still cause health problems. Getting tested for STDs is the only way to know for sure that you are not infected.
