To make a very long, embarrassing story short, I was involved with a man and he wasn't who I thought he was. We never engaged in unprotected intercourse, but we had engaged in cunnilingus and fellatio more times than I can remember over the past six months. I *might* have had a small canker sore once when we had engaged in it (irresponsible, I know, I'm sorry). Thankfully, he never ejaculated in my mouth but did pre-cum at least once or twice.
I have experienced nothing abnormal after any sexual act with him, and our last one was 11 days ago. What is the likelihood of HIV and other STDs from the encounters I've described? Could any open cuts make a real difference in either fellatio or cunnilingus? I plan on getting tested to cover my bases. Is a six-week result accurate or should I go again after the standard 12 weeks or even longer?
