Sex is important. So is your health. See how you can own your sexual health by knowing your status and prevention options, getting tested and retested, and more—because healthy sex is great sex. Check out Healthysexuals.com and talk to a healthcare provider to learn more about your options, including condoms, getting tested for HIV and other STIs, talking to your partner(s) about healthier sex, and prevention medicines including PrEP (pre-exposure prophylaxis). Also, you can find out about sexual networks and how they play a role in your sexual health. If you’re living with HIV, talk to a healthcare provider about HIV treatment and how it can help prevent the spread of HIV.
