Risky exposure, do I need testing? Should I be concerned?

[marcus360]

I have been concerned for the past 3 months about a possible exposure.
Last march 2017 I had unprotected sex with a friend of unknown status. I had two HIV tests, one 3 months after exposure and the second 5 1/2 month after exposure, both being negative. But between those period I had PROTECTED sexual intercourse with the same person numerous times.
In December of 2017, I received oral intercourse for the first time from the same girl, and from the end of December till 8th of January had 4 PROTECTED sexual intercourse with her. However after the last time, I noticed a small cut near the shaft of my penis (no blood, just a small wound/cut). In the beginning I thought It was herpes, but the wound dried up and disappeared less than 48 hours later. I am worried whether the cut was due to the oral intercourse or probably hurt myself from removing the condom. I only noticed the cut the next day while masturbating because I felt a little pain while doing it.

Should this worry me? From all the exposures I had, am I at risk of contracting HIV?
I had a little cold 2 days ago with an awful dry cough, and I am usually never sick. but since it marks almost 3 months since my exposure, is it possible that my immune system is already trying to fight off the virus?

Please give me answers as I cannot concentrate on my work and keep thinking about this.
Thank you.

As an adult, the only risks for HIV are:
1) having unprotected, penetrative vaginal or anal sex, or
2) sharing IV drug needles with other IV drug users.

If you don't do either of those activities, you will NEVER have to worry about HIV.  There is no detail you could add to this event that will make it a risk for HIV.

Your other exposures are covered by the tests.  ANY test you take 90 days or more after the event are conclusive, and negative.

The protected exposures, even with wounds, are of ZERO concern.  No HIV risk, no matter what detail you add to this event.
