How early can an hiv infecter person infect anothe person?

[JustinT1]

I was tested December 13, 2010.  Then again February 2, 2011.   Both those tests where negative, throughout the holidays I did not have sex.  On January 5, 2011 I had unsafe sex with a guy.   On January 12, 2011 I had unsafe sex with another guy.  That's it in the past 6 months.  The January 12 guy tested positive.  I got a text from him telling me.  The Jan 5 guy says he's negative, although I don't quite believe him.  The only way I could get it was if I got it from the Jan 5 guy then gave it to the Jan 12 guy.  Both times I was only the top.  I did not even suck them.  I just topped.  The guys are 7 days apart.  Is it possible to get infected and then infect someone 7 days later?  Is it likely, highly unlike or just possible?  Also, say I was infectious at day 7.  Wouldn't that mean it was moving along fast and I'd develop antibodies fast?  Meaning, that I'd likely test positive at day 29?  The average person will test positive around day 30, some as early as two weeks.  Since I tested negative at day 29, will I likely test negative again next week when I get tested?  I just want your opinion.  Facts are:

-both times I topped
-is it likely that a guy can infect another guy at day 7?  I was told by my doctor friend that at 7 days a viral load would be very low and that infecting someone would be highly unlikely.  What do you think?
-if I was infection at day 7, wouldn't the HIV be moving along fast and have antibodies fast, meaning a positive test at day 29 was likely?

I know the risk is high, but since I have such exact numbers, and I was tested all around the time I was at risk, I'm wondering if you can give me an estimate of how likely I am to test positive.

And if I test negative next week, I won't have unsafe sex with ANYONE. I'm scared to death right now.

So, you survived from April 1984 till April 2005 without taking medication!  I had heard hiv+ people only lasted on average 7 years without medication.  How's your prognosis?  How much longer you expected to live?   Again, if I'm being intrusive, don't answer.

Do your tests as you have planned. A negative test result will be conclusive at that time.

I went on medication in April 2005.

You've lasted 27 years then on medication.  Are you still healthy?  How long do your doctors think you'll have to live?  If I'm being intrusive, you don't need to answer.  I'm looking at this now from both sides.  I hope I test negative, but I also need to look at the possibility of testing positive.  What worries me most is how long I'm expected to live if I test positive.

If Jan 12 was your last exposure that means a test tomorrow would be 7-8 weeks after exposure. Antibody tests are extremely accurate at that time. It wouldn't be false hope because it would be very rare for a negative result to change at the 3 month mark, if it does turn out negative. You would still need to test in April but you could walk in feeling confident of another negative result. It's a much better option than posting on forums over the next few weeks speculating about things, because that will get you nowhere.

A normal life span if you take care of yourself. No one knows when there time is up but you don't have to rush it.
