You have posted several times regarding very low risk exposures with people you do not even know have HSV2.
There is no need to have such anxieties regarding sexual contact, especially protected contact or even unprotected contact with a partner if you have mutually tested.
From what I have heard an initial herpes infection starts out with sores and not feelings. Recurrent outbreaks may begin that way but not the initial.
A low grade fever does not necessarily mean an infection either and I don't think the two are related.
If you want you can test in 12 weeks for peace of mind but I think it would be negative.
