Two Thursdays ago I went to see a South Korean massuse/csw.  During the session we kissed heavily ( with tongue). 5 days later I found what looked like a papule on the side of my tongue a little more than half way back,it seemed to be an inflamed taste bud. I clipped it off. 2 days later in the same spot I noticed a sore with white edges that looks a bit like a chancre. Is it possible that I could of opened a syphiles chancre. It was open by day 7 after contact. The sore is not painful. I have read some places that the timing is to early and others it can occur? Is it being so early enough to rule out syphilis? Over the last 5 days it has been healing and is getting smaller. During this time I have not kissed my wife with tongue ( or at all) and my daughter I have only given pecks on the lips and have shared drink cups. If I did have syphilis would I have put them at risk? Should I just think of this as a traumatic ulcer
