Hello and thank you for your question,
It is very unlikely for your blisters to be anything else other then herpes. Although herpes are usually painful, they dont always have to be. There are really no other infections which will produce symptoms similar to what you have described.
To know for sure, it would be best to see your doctor as soon as possible while you still have a blister (before it scabs) so that a culture can be taken. Culture will confirm the kind of infection you have.
If indeed you had herpes, your symptoms may come back frequently or not again for several years, there is absolutely no way of predicting. However, if herpes is confirmed, you should have anti-viral medications on hand in case of future break outs.
I hope you find this information helpful. Please feel free to follow-up with any other questions you might have.

I was thinking of writing you in my initial reply that there is no way of knowing if you caught this from her or if you had in your body prior and it was just being dormant (sleeping) and "woke up" just now.
However, even though there is no guarantee, this infection did come from her. I would suggest that she also gets tested (blood work).
The only other possibility that your symptoms could be is what called folliculitis, which is infection of the hair follicles (similar to acne on the face), however, the fact that you had one lesion on your shaft (where there are no hair follicles), kind of goes against folliculitis diagnosis.
I know that you probably dont want to hear that it's herpes but it is unlikely for it to be anything else.. I am sorry. Your symptoms are classic for herpes presentation (except for no significant pain). However, good news is this is not life-threatening and another outbreak may never happen again or can take years before happening. There is good treatment available for symptoms of active outbreaks (such as Valtrex).
Let me know what your test results show and encourage your girlfriend to get tested as well.
I am glad I am able to help you.
Folliculitis is basically infection in the hair follicles caused by a bacteria. It is similar to acne which people get on the face or chest. Folliculitis looks like pimples which would also scab and eventually go away (within a week or so). Applying antibiotics to them will help them heal faster.
Folliculitis happens when these hair follicles are damaged by friction from clothing, sweat, and/or shaving.
Here is a link to what folliculitis looks like: http://www.dshs.state.tx.us/idcu/health/antibiotic_resistance/mrsa/picMRSA/folliculitis5.jpg
So, yes, it is possible that you caused yourself some irritation, friction and infection. If that's the case, it would be great as these are not contagious and are not considered sexually transmitted at all. Lets hope that folliculitis is the cause of your symptoms.
