Having HSV-1 is common, and it doesn't mean you have to avoid intimacy. Your question is about the risk to your partner, so here's what the evidence generally shows.
HSV-1 is most often an oral infection, usually linked to cold sores. If your infection is only oral, receiving oral sex is generally considered low risk for passing it to a partner, because the virus isn't typically present on your genitals. If you have HSV-1 on your genitals, whether from oral-genital contact or an outbreak, the risk to a partner's mouth is higher, especially during outbreaks or periods of viral shedding. Shedding can happen without visible symptoms, so the risk is reduced but not eliminated. Barriers such as dental dams, avoiding contact when sores or tingling are present, and daily suppressive antiviral medication can all lower the risk. A healthcare provider can help you understand where your infection is located and whether testing would clarify your situation, since the site matters a lot for estimating risk. Many people with HSV-1 manage it well, and a clinician can give you guidance tailored to your health.
