Dont worry about it . Condom protected sex is protected sex . I had the same thing happen to me . P.S. when we all drink alot of water it comes out clear .
Also, I've been having a slight itch around my anal area, but nothing severe, just causes discomfort from time to time. Whenever I drink a lot of water the urine comes out clear. So far there has been no case of any discharge or etc. so I think I'm ok but the fact is that this 'incident' occurred after intercourse, so maybe everything just came together at the wrong time
One thing about my situation, after this encounter, I started to go to the restroom more frequently and more urgently, however when I did go, a little or no urine came out and is still continuing for about 5 days now; however it has gotten better to some degree. I went to the hospital and they gave me medication for gonorrea and chlamydia, did a swab, and doing further lab tests on my urine. They told me if they don't call me everything is fine and they told me they will get back to me by tomorrow. I don't know if this is an anxiety problem as well, because I am a pre-med student and last week was the craziest week of my life with midterms and etc. I don't know if stress has to do with it but one thing I realized the more I'm sane the better I feel so I don't know. They already gave me the medications in case it was either chlamydia or gonorrea but I don't know if I should worry about HIV and others as well. Since you say I was never at risk for receiving unprotected oral sex then I should just let it go..

You were never at risk in the situation that you've provided.
