>Should every single person with an std be castrated for the greater good?most adults have herpes. not necessarily genital herpes. if you get "cold sores" that is face herpes. if you give someone oral sex they could get genital herpes from your face herpes. You usually get one or the other. it is very rare to get both. the immune system usually prevents you from catching a second kind. I got face herpes from my own mother. It's a shame because I love giving women head.
