STIs
Sexually transmitted infections (STIs) are extremely common among people who are having sex, though people don’t always talk about it. It’s important to know your risk factors and engage in sex in ways that you are comfortable with.
If you’re having sex, we recommend that you get tested every three months. Getting tested is the only way to know if you have an STI.
There are different types of STIs: Some are caused by viruses, some are caused by bacteria, and some are parasites. Here are some resources that will help you learn about a few of the most common STIs we’ve seen.
- Hepatitis A, B and C
- Chlamydia, gonorrhea and syphilis
- Herpes, anal or genital warts (HPV) and crabs
