Various low risks along with rash on chest

Let me first say I am probably a little extreme when it comes to worrying.  This isn.t the first time I have been worried about hiv.

Anyway.

A few weeks back, I received a 2.5-2.8 months negative test result after receiving unprotected oral sex (I am male).  That was encouraging and I felt okay to move on.  I should be able to move on from this situation...right???

Now I am freaking out again!

About 11 days ago I received unprotected oral sex and fingered this girl with an unknown status.  I remember having a few tiny cuts/scratches on my fingers, but they seemed to be close to fully healed.  I also gave and received hickeys, BUT the girl who gave me a hickey went too far and broke my skin...she actually tasted the blood.  It wasn't a bunch, but was visable...would that be considered a risk?  I also gave a hickey and now I am thinking I also broke skin and tasted blood.  Would that be a legit risk?

Normally, I wouldn't get this worried about these low risks, but I now have a rash on my chest ranging from my pecs to mid stomach...and the rash seems to fit the same characteristics on an hiv rash.  Small raised red dots.  I know it is indeed a rash.

How long does an hiv rash last for?
I haven't been experiencing other symptoms...no fever or flu like (altough I freak myself out searching for swollen nodes...I always think they are swollen).
Would a hiv rash develop this early?  11 days after exposure?

I did sleep with my shirt off and with someone else's blanket the night before I discovered this rash so I am really hoping that is what caused this rash.  I normally sleep with my shirt on and I use my own blankets.  Could this just be a crazy coincidence?  Should I stress over this rash and these hiv risks...please help.

Thanks in advance.

At no time were you ever at risk of contracting HIV. As for your rash see your dermatologist. It has nothing to do with HIV.

If it were a hiv rash, how long would it last and when would it appear?

Well, my rash has practically cleared up now.  Took about 4-5 days.  Wouldn't an hiv related rash last longer?

Sorry for being so worried, but I need to know.  Thank you for your time and energy!
