You did not do anything that would put you at risk of acquiring genital herpes from her. You were very cautious.
I think what you need to find out is if you have either HSV 1 or HSV 2 already. The test that you want is an IgG antibody test – under no circumstances should you obtain an IgM test. They have many false positives and make people fearful when it is not necessary.
The symptoms that you are describing are very likely due to you over observing your body for signs that you have acquired genital herpes. If you go farther with her sexually, my guess is that you will continue to notice every little thing in that part of your body, which normally would not have been noticed by you, much less a concern. This is a pretty typical reaction for someone having new sex with someone with herpes.
Once you get your antibody test back, you will know more about how much you need to worry, if at all. You can also order an IgG antibody test for HSV 1 and 2 online at many testing sites if you would prefer to go that route, might be easier in the long run but they often don’t take insurance for payment.
You have two more questions so let me know if there are other things that come to mind.
