Urethral Redness - STD

If I got a handjob, then the next time I urinated there was slight tingling/burning accompanied by slight urethral redness (this was probably less than 15 minutes afterwards), is there any chance it was STD or infection related?  Or, what are the chances?  There were no visible signs of cuts, warts, etc. on her hands; and, I did not see her make contact with her mouth or face.  I assume the redness could have been lubricant related, though it was baby oil, which usually doesn't cause irritation.  I think I'm just paranoid, and I assume that STD symptoms typically don't manifest themselves this quickly.  The redness and tingling/burning went away the next time I urinated and have not returned.  Any thoughts?

It's just irritation from the hand job I"m sure.
