Okay, so a few weeks ago I had vaginal sex with a condom with a partener I had known for close to a month. After the sex I had removed the condom and we were sharing a smoke which she dropped on my penis accidently (there was more than a little alcohol consumed prior to our intercourse). I received a burn although I was unaware at the time. Afterwards she offered to kiss it better and we proceeded to have unprotected oral, vaginal and anal sex. When I woke the next morning there was a burn on the top of my shaft where the cigarette had fallen. The burn has healed, however I am concerned about whether I may have contracted something while having anal sex with her. I have not noticed any symptoms and my partner does not have any STDs. What are the odds that I have contracted something? I'm very concerned and have a Dr. Appointment tomorrow to be tested, but if anyone can give me some info to ease my mind sooner I would greatly appreciate it.
