I had a cold sore on july 15th. on august 19th a month and four days later i performed oral sex on my partner what is the chance that she will get herpes down there? ( i have performed oral sex on someone else before and they did not contract it ?

No cure.: The thing with Herpes, is that it never truly goes away. The super contagious sore may be gone, but the herpes virus is still living in the nerve cells of the mouth. There are studies suggesting that occasionally just before an outbreak, herpes virus can be found in the saliva. Prevent by using condoms or dental dams, getting regular STI tests and having reduced numbers of sexual partners.
