If you are sexually active, it is important to get tested for STDs on a regular basis. Depending on your risk factors, you may need to get tested more or less often. If you have multiple partners or do not use condoms regularly, you should get tested every 3-6 months. If you have one partner who is also monogamous and you use condoms consistently, you can probably get away with getting tested once a year. However, if you or your partner has any symptoms of an STD, it is important to get tested right away.
