Welcome to the forum. Did you read the Disclaimer message or, as it suggests, read other threads with the same questions? To repeat some facts that have been discussed innumerable times on the forum: your partner had HIV probably is zero or close to it, if she isn't a commercial sex worker, injection drug user, or otherwise at high risks; condoms reliably prevent HIV transmission; almost nobody catches HIV by oral sex; and no symptoms are useful clues about new HIV infection (and yours don't sound suspicious for HIV anyway). However, if you would like to provide more detailed information about your partner, I can more accurately assess that part of the risk. But the bottom line is that most likely you have no worries about HIV.
The genital ulcer does not suggest HIV but still might be important. The most common overall cause is genital herpes. You describe some atypical aspects of that disease, because catching herpes despite condom use would be unusual; most new HSV infections cause multiple penile lesions, not just one; and there are hints from your description that this sounds more like a pimple. However, to be safe you should see a provider for clinical evaluation and testing for herpes. When you do that, you may as well go ahead with an HIV test as well. Almost certainly it will be negative, but you'll probably sleep better knowing that.

With regard to my penile symptoms, the genital lesion did not look at all like a pimple; it scabbed over very quickly and itself was not raised. However, the square inch of skin surrounding it became fairly swollen. This does not change your analysis with respect to the possibility of HIV contraction, does it?
Among women like you describe ("sexually active college student at a small private Midwestern school" -- exactly the same sort of place I attended all those years ago), I would guess not 1 in 10,000 has HIV, maybe not even 1 in 100,000.
That's all for this thread unless and until you want to come back to report your test results for herpes, HIV, or both.
Sorry to again bother you, but I still have some anxiety about my already discussed episode. My concern now is that my symptoms were caused by syphilis. I did not undergo syphilis testing. Since my episode, I have taken 45 doses of 100 mg Minocycline in connection with my treatment for acne. I have read that taking antibiotics can affect syphilis test results. If I test for syphilis, will my minocycline medication lead to an inaccurate result? Furthermore, would the minocycline eradicate the syphilis from my body?
You may not keep returning to the forum with anxiety-driven questions that are best answered by your personal health care provider. That's all for this thread. Any more and I will immediatley delete the entire thread.
