I sometimes see escorts and have given oral to them in the past (female escorts) I also get coldsores from time to time, maybe 3 or 4 a year, two days ago I felt as though I was getting a coldsore so I put aftershave on it and used coldsore cream straight away several times in hope of stoping the 'coldsore' now it's not come like a normal coldsore its a circular Mark that looks similar to a burn on my lip like if I had put a cigerette out on my lip, is this possibly a syphilis chancre or have I just stoped the coldsore and due to the aftershave and coldsore cream its stoped it coming? Slightly worried, thanks In advance
