it's called an std for a reason hon. if all it took to get was touching the same object then we would all have it and it would be a non-topic by now. the virus doesn't live very long away from the body. that is to say that technically the surface of your skin is"outside" of your body but contact with the infected area of your skin can spread it. always wash your hands and try not to let anyone come into contact with the area of infection if at all avoidable. the germ killing properties inherent in soap will stop the virus then and there. i definitely wouldn't share the same wash cloth but that's more of a general hygiene rule anyway. the risk from the soap is nil the risk from sharing drinks utensils lip balm are much much higher.
can someone spread genital herpes by sharing a soap with family members either in the shower or sink?
