What are the risks of HIV infection for the passive partner of oral sex?

My question is about AIDS/HIV: I had a sexual affair that lasted two-and-a-half months, and, unfortunately, I was not using condoms. I happen to know nothing about my partner's previous sex life. I know that, for a test to show something, you must wait for six to nine months. I would like to know whether, provided that I am infected, I will experience any symptoms in this six to nine month period? Is it possible to have the virus and not have any symptoms or indications all this time? Right now, I am a graduate student and I am experiencing anxiety, fatigue, sleepiness, weight loss (three to five pounds in the last two months). Are these related to the disease, or is it just in my mind?

Can puberty blocker effects be reversed? If so, what are the lasting effects of reversing the treatment? Would the child have emotional and physical scars?

What are the signs of an advanced case of syphilis, say twelve years down the road? Is treatment still possible or is it too late? I have reason to believe that I've been infected that long, and denying it. Would I still be contagious? Would I have been after five years?

1) What are the symptoms of gonorrhea?

2) How long of a time frame could you have gonorrhea and not know it? The doctors say you can't track how long you have had it so how do we know? I feel my last partner gave it to me and that was nine months ago. Is that possible?

Thanks. I can't get much information in regards to this subject so I have no idea. And it can't be received from sitting on a toilet or anything of that sort, correct?
