No, you cannot spread them to your face. The virus will go dormant in your body but it will never leave. You may be infectious some day or not. No one can tell you the definitive answer. If your immune system is low due to stress, lack of sleep, booze episodes, severe colds, the warts may return. If you have sex with someone 10-30 years from now and if you get new warts, you will not know if they are from the old infection or its a new one infection unless the strain number is the same. If possible, ask your doctor to get the strain number associated with the warts in case you get new ones one day. No need to be scared. No one has ever died from genital warts.
