About 2 years ago I had a brief drunken encounter with a man in which I performed brief oral sex with no ejaculation, we attempted vaginal intercourse unprocted but I am a virgin and he was unable to penetrate and again it was very brief, we attempted another position from behind and his penis entered my anus do to him not having his glasses on and it being completely dark, once it was realized that this was the wrong entry we stopped, again lasting all of maybe a min or two, with that being said that should of been a sign to call it a night, instead he performed oral on me briefly. I have not been tested and hadnt had any kind of symptoms but its been in the back of my mind. Now, let me bring you up to date, about a month ago I had an unprotected oral encounter with a man, just me giving oral, no ejaculation, very brief and about a month or more later I noticed what I call canker sores in my mouth, one one my gum and two in the back of my mouth on the roof. Let me say that I am a smoker about a pack a day and drink several times a week, so I dont know if that has anything to do with it and I have had a very stressful living environment for months, needless to say I am very worried and would like some insight. I have been tested and waiting on results. Tested for herpes and HIV, I am concerned if any of this has anything to do with my encounter from years ago or my most recent encounter or entirely unrelated. Also, based on pictures I have seen of herpes, they dont look like what I believe I have which is canker sores, however upon examining the doctor said she was going to test for herpes. If you could provide some insight
