This for me atleast is very true. I had oral sex with someone who was asymptomatic and I believe it contracted onto my genital region. A good way of telling if you are shedding (i forget where I read this) is to apply hydrogen peroxide to the PREVIOUSLY affected area. If no sores exist but there is vigorous bubbling then there is a CHANCE you are shedding. I treated my affected areas with DMSO/H2O2 with and without sores present and there are times when the hydrogen peroxide is reacting with the virus when no sores are present. Its a lot more stealthly than expected. Sorry wish I could write more but I have to run. Good Luck. Hope this helps.
