Welcome back to the Forum. The sore
spot on your tongue
is not syphilis-I am confident of this. It is unlikely that your partner had syphilis or, for that matter, any other STI. Further even if she did, most STIs are not transmitted through a single exposure. Most importantly however, syphilis lesions do not typically occur in less than a week after sexual contact. The average time for syphilis lesions to appear is three weeks (21 days) after a sexual encounter, not after just six days.
