Is It Possible Be Have Something Mistaken Have Herpes, I

is it possible be have something mistaken have herpes, i have never had sex . i was molested as a child but this was 12 years ago and these sore have only really been active for maybe two years and i didnt go to the doctor cause i assumed it couldn't be a std due to my not being sexually active . is it possible for these things to only show up 12 years later or is it possible for me to have something else that when seen my doctor assumed wrong
