You realize most people don't get any symptoms, right? Many people contract it as a kid (a kiss from a relative) and their immune system suppresses it. Unless you get an HSV blood test you will not know.
Even blood tests are unreliable. IIRC, IgG tests are quite reliable but not every clinic does them. Many clinics default to an IgM test, which are useless[0]. The gold standard here is the Western Blot test
