If open sore--yes!: It doesn't matter "where" the kiss is, it matters where the open, moist, infected viral particles exist that can enter a tiny opening (yes, even "chapped" lips may be enough) in your lips, making you the next infected person! antiviral medications and waiting until lesions are healed can minimize the risk of infection being transmitted to others, regardless of lips or genitals.
