Did you have these lesions swab tested? This is the ONLY way to know if these particular lesions are herpes. If it is has been going on for three weeks, it may be too late to do any accurate swab testing. Runny nose and sore throat are not normally part of a herpes symptom set.. I do not believe that if the only contact was frottage that you would get oral symptoms, that doesn’t make much sense to me.
