If you have never had sexual contact of *any* kind (this includes touching/oral sex) then there is probably no reason to believe that this is herpes. Although on one can tell you what it is that you have. You have to go to a doctor and have a blood test for herpes. A lot of doctors are very ignorant about herpes, but if you insist on a blood test, they have to give you one.
It's kind of funny how everyone is afraid of doctors and is just like, "Do I have this or that?" And the worrying is what really gives them the problem. Anyway, it's better to be safe. Good luck to you.
