Reacting to the title of your question plus the opening few words, before I look at anything else: They call them STDs because you have to have sex to transmit them, and for that purpose hand jobs don't count. And this has been far more than "touched on": it has been discussed extensively. What I don't quite get, even after 4+ years of doing this forum, is questioners' capacity to think that their own cases are somehow unique.
OK, now I have read the rest. Guess what? There was no risk for any STD. You even describe someone who apparently made special efforts to be hygienic. And when someone suggests his or her own symptoms likely have a psychological origin, usually s/he is correct -- therefore I tend to agree with your suspicion about the "warm" and "strange" feelings in your urethra.
If you are not sufficiently reassured by this reply, it is fine with me if you decide to get tested. But if something turns up positive, it will not be from this event.

Pay attention to the source. You won't find many professionally run medical sites, and especially none that are professionally monitored, that describe hand-to-genital contact as an STD risk.
One other question... At one of the strip clubs I went to during my bachelor party a few weeks ago, a stripper put my fingers inside her to see how "wet" she was. Is there any risk of an STD in that situation?
Sounds like a pimple. Doesn't suggest any STD. See a provider if you are concerned.
It does not matter what symptoms you might get from here on out. They will not be due to an STD from the hand job. Stop the self-examinations.
End of thread.
