Unfortunately I gave a guy a blowjob, it was for a few seconds which I think it does not matter :/ he did not have any sore on his penis, about a week after that I had one sore on my inner lip, it left about 2 days later and its been coming back on and off for like 3 weeks. I also have another sore on the side of my tounge. Can this be herpes? How soon after incident do sore develop? What r the chances of getting oral herpes by this incident? How long do they last? And do they come and go with in weeks? Thank you so much :) take care
