Welcome to the forum.
This exposure carried no risk of HIV. First, HIV is rare in women like your partner. I can't say the risk is zero, given that she apparently is in the habit of having sex with men immediately after meeting them. But HIV is really rare at her age.
Second, even with completely unprotected and successful intercourse lasting several minutes, if the woman has HIV, the risk to her mail partner averages once for ever 2,000 events. Given the very brief genital contact, with little if any penetration, you risk would be far lower than that.
Other STDs are somewhat more likely -- your partner is at high risk for chlamydia and perhaps gonorrhea. But here too, the very brief and superfical contact probably was risk free for practical purposes.
As for your genital symptoms, you don't say exactly what you're feeling. But for the reasons you note yourself, I'm pretty confident they are just your anxieties magnifying trivial or entirely normal body sensations.
Having said all that, I suggest it's a good time for you to be tested for the common STDs: visit your local health department, Planned Parenthood, student health clinic, or private doc and have a urine test for gonorrhea and chlamydia and blood tests for HIV and syphilis. Most likely they'll all be negative. But relationships break-ups are notorious times for elevated STD risk. Even though your recent event carried little or no risk, given that exposure plus your recent break-up (perhaps with the possibility your partner had begun seeing other men) this seems a good time for routine testing.
I hope this has helped. Best wishes-- HHH, MD
Thank you very much for the quick response once again! Do I need to keep a look out for any more symptoms in my genital area or should I stop stressing about it?
OK, I agree no need for additional STD testing. And you definitely don't need HIV testing on account of this event.
Thanks for the quick reply! I was tested before the relationship I just ended and everything was negative. There was no cheating in the relationship so that leads me to believe that I hadn't picked anything up during the relationship. Should I just get tested for chlmydia and ghonerea carrying the low risk that you just stated, it would make me feel a lot better if I could have you say that I don't need hiv testing after this particular event showing no symptoms over the past 2 weeks.
Stop stressing. Time to move on without worry!
Another quick question, i mentioned in my first post about the excess urine after urination the odd time, mostly in the morning but this is only worrying me because of the event that occurred 2 weeks ago if that hadn't have happened im sure i wouldn't be stressing, but the last 2 days i have noticed shortly after my morning urination a tiny drip of what looks like clear somewhat cloudy i guess you could say you can feel small pressure than it comes out, no burning, no itching, etc... I have read a post similar http://www.medhelp.org/posts/STDs/Clear-Discharge/show/765928
and i feel like it might just be something similar to this.
I also have not masturbated in approx 3 days if that has anything to do with it. Once again though no burning, no sores, nothing physically wrong just the little bit of drip in the morning shortly AFTER i urinate and sit down/relax.
Usually this is leftover pre-ejaculate fluids from a normal nocturnal erection, and it indeed might be more prominent if there has been no recent ejaculation. If you're convinced it's new, get professionally evaluated.
That's going to have to end this thread. You may not keep returning with unending questions. As I said before, it's time to move on.
