Hi There,
I understand you worry but you had protected sex, - even if the lady had HIV (which we do no tknwo for sure) as long as your Condom stayed over the tip of your penis during penetration you are fine.
Do not worry about small cuts, if they were open they would be bleeding, if your cut was fresh with blood escaping and you had direct contact with blood escaping from a HIV infected person, it would still be extremely hard to catch it this way.
You do not need any more tests as you had a no-risk incident! :)
Kudos for using the Condom- keep up this good work and you will not require another test as it is then no risk...
You really are okay and do not have HIV from the above! :)
As for symptoms - ignore them - they do not diagnose HIV and are widely mis-reported across the web - you are fine! :)
Best Wishes
But do see your doctor about the blood and mucus in your stool, which could be serious health problem. Assuming you have not been on the receving end of anal sex, it cannot be an STD. It has nothing to do with the sexual exposure mentioned.
And by the way, it's BS that your wife will know about any of this if you see your own doctor, no matter how small the town. That would be a federal crime with a penalty of at least $5,000. It never happens.
