Wow, I think we stepped over a big portion of this question. If she is std free then you don't have any stds...you can't nessecarily get an std from kissing unless the girl performed oral on you, and most likely so I still doubt to think you can get an std from her if she is in definite std free. Assuming that you were kissing her, that you had gotten bumps around your mouth in which is cold sores that are also mentioned to be herpes and this is generally common for quite a few people to have 'herpes' around the lining of their mouth. cold sores can be quickly and easily transmitted by kissing or even drinking someone elses previously drank beverage. If it is bumps on the shaft of your penis, and they are white...like previously stated, more and likely they are just glands.
Also, keyword: virgin. unless there is foreplay, there is about a zero chance of getting any stds from a virus carrier. Like Eiri had said, you cannot get an std while masturbating with no contact of the actual virus from whom who is postive of stds.
It's common for people now a days, for them to go onto the internet and look at the symptoms of each std, comparing their issues and think worse of their problems.
