Doctors like to bring up herpes for strange reasons. Cervical erosion doesn't have much of anything to do with herpes, or any other STD, but it is good to rule those things out as causes of cervical bleeding.
Most of the time, it's just hormonal changes causing it.
You can get herpes on your cervix, and you'd have some spotting or discharge. I doubt that's what this is with ghsv1. I also doubt you have ghsv2 if you've only had the one outbreak.
I'm sorry she even brought it up. :(
