You're thinking logically about this, and you're right to question it—this is actually a really common point of confusion.

Here's what happens: **HSV-1 can absolutely cause genital herpes.** If someone with oral HSV-1 (cold sores) performs oral sex on a partner, they can transmit HSV-1 to the genitals. So you'd get HSV-1 genitally, not HSV-2.

You wouldn't get HSV-2 from someone who only has HSV-1—the virus type doesn't change. HSV-2 is typically acquired through genital-to-genital contact with someone who has HSV-2.

**The key point:** Both HSV-1 and HSV-2 can cause genital herpes. Clinically, they behave similarly in that location, though HSV-1 genital infections tend to recur less frequently than HSV-2. But either type can establish latent infection in genital nerve cells.

If you have concerns about potential exposure or symptoms, a healthcare provider can test and identify which type through PCR or serology—that clarity matters for understanding recurrence patterns and transmission risk going forward.

Does this clear up the distinction?
