Worried about STD

[Throwawayanon]

About 8 weeks ago I gad a brief encounter with another man.  He performed unprotected oral sex on me briefly and then rubbed his anus on my penis briefly.  Probably about 30 seconds each time.  I was never more than semi erect during any of this, and probably even less erect during the frottage.  At 4-1/2 weeks I tested for all major STDs, and all were negative.  I have not had any symptoms that I am aware of and no sores or canchres or anything that I have noticed.  The last few days the opening of my penis has seemed slightly more sensitive.  No redness.  No burning or discharge.  Just seems somewhat tingly.  I am wondering if I am just obsessing and it is making me think my penis is more sensitive or that there is something going on where it isn't.

I have read several articles and they mostly indicate that although not zero risk, oral sex is not a very efficient transmission method for STDs.

Am I making myself crazy?  Is a full board of negative test results at 4-1/2 weeks a safe bet?  Thank you.

Thank you.  I'm trying to calm myself down.  There was nothing for weeks and now all of a sudden I have this sensation.  It doesn't make sense to me logically that I would all of a sudden develop a STD or UTI after testing negative a month ago, and yet here I am.  I will do my best to trust the test results and move on with my life.

All your symptoms are typical for the physical manifestations of anxiety. You don't have any infection and no, you can't cause an infection through worry.

In any case, there's nothing more I can help with.  If you remain concerned, return to your doctor.

I can't shake the feeling that something is going on with me.  My penis continues to seem to be very sensitive right at the tip...I can feel it, if that makes sense.  Not all the time...I guess dot is mostly when I think about it and start getting worried about things.  No redness except that may be I have been touching it more than normal lately.  No discharge that I have noticed, and it doesn't hurt when I urinate.  I feel like I have been urinating more than normal, but they have been normal flow, normal amount, etc.  Again, negative STD test results four weeks ago.

Is it possible that I am creating step thing by worrying about it so much?  Is it possible to give yourself a UTI by worrying about it?  I have been very stressed for the last two months, for a variety of reasons.  Am I causing this to myself?

Thanks for the response.  When I think about it logically, it makes sense: low risk activity, he told me he had been tested, was disease free and always played safe, negative results, etc.  My guilt has been getting the better of me, I think.  I just needed to hear someone tell me that my thought process was sound.

The information you found in "several articles" is correct. Oral sex can be considered safe sex. The risk is low for all STDs and zero risk for some. And with the negative STD tests at 4 weeks and no symptoms by 8 weeks, you can be sure you weren't infected.
