5 (five) weeks ago I had a massage by a male masseuse.  Regrettably it escalated into some semi-deep kissing.  I also briefly licked his testicles.  No oral or anal sex.  I know from past postings that these activities are considered very low risk for STIs.  2 days ago I noticed some white patches/spots inside my left cheek.  Also a few spots on the right.  The whiteness pretty much disappeared by the next day, but there remains a small, slightly sore red patch on the left side that looks like an abrasion.  Very smooth and soft.  I happened to have a dentist appointment yesterday and the hygienist examined it.  She described it as an irritation, possibly from food, mouthwash chemicals, dental topicals that were used on me a couple days before, etc.  Today, it looks a bit better but I am a little worried about syphilis (although the lesion evolution, timing and appearance seems much different that what is described on the internet).  I would be interested in your thoughts as to how worried I should be given the exposure and my description.  Thank you very much.
