STDs and Infidelity: Understanding Your Risk After a Partner's Cheating

Yes.

Sexually transmitted diseases (STDs) can be transmitted through unprotected sex, including anal, vaginal, and oral sex. If your partner cheats on you and has unprotected sex with someone else, they can contract an STD and then transmit it to you when they have sex with you.

It's important to practice safe sex to protect yourself from STDs. This includes using condoms, getting tested regularly, and talking to your partner about your sexual health.
