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.

Gay sex, Straight sex makes NO difference! Use condoms!

Regardless, this experience changed me.

If I test positive, the change is obvious.

If I test negative, it will forever change the way I view gay sex.

I'd say 98% of guys do selectively bareback.  Either with their bf's, a guy they are exclusive with or a guy they feel they can trust.  Most will eventually end up in the same situation I'm in, wondering if they are at risk and hiv+.  

I wonder how many of those guys would turn down an attractive young guy that says he's hiv negative, tested a few weeks ago and that he hasn't had sex in over 6 months.  Unfortunately, most guys would say yes to him.  Its why hiv is so high.  Guys don't see that in the gay world its DTA (Don't Trust Anyone) or you'll end up one day at risk of getting hiv.

Welcome to the real world.

True, but if he would have told me the truth.  (again, assuming he really is hiv+)  Then I would not have even had sex with him.   I did not lie, my flaw was poor judgment.  I shouldn't have believe him.  I just can't believe so many guys will flat out lie like that about having something as serious as hiv+.  It wasn't even a small lie, but a long detailed lie to get me to do him bb.

After this, it really comes down to not being able to trust anyone for unsafe is.  Its always use a condom, or you'll likely end up with hiv+.  Too many guys out there that are hiv+ lie about it, then you need to factor in the hiv+ guys that are hiv+ but don't know it.  Nowadays, it truly is impossible to feel safe having unsafe sex with anyone.

Mistakes happen when condoms fail. Not using one is not a mistake, that is just a poor judgement on your part.
