Yesterday I had "oral sex" with my partner, so far it's all good, but today when I woke up I found a one, small, non painful sore in my mouth (besides my tooth). My partner has no symptoms to be infected with HSV (not sure about that) does that means that it's for sure he has HSV and I got it from him, or it maybe just a coincidence. Also, is there is any test can I do to check.
Please I need answer I'm so terrified
