Saw a female SW in Montreal in May - 2 appts in 3 days, with unprotected oral (receiving and giving) and vaginal sex with condom.  Did Chlamydia & Gonorrhea tests with STDcheck 9 days after my encounters and they were negative. Maybe 4 wks after encounters I started to notice sensations in my urethra during urination, like the whole length of it was more sensitive.  Not painful, but sometimes maybe almost “warm” or tingly during the start of urination.  Also, sometimes after sex the urethra seems sensitive at the tip and inside the shaft if squeezed.  I have not seen any discharge, but haven’t really been looking.  Most of the time, urination feels normal.  Just different sometimes, like first thing in the morning.  Should I retest?  Was I too early to test when I did it (at 9 days)?  Could I have NGU causing this feeling and would that pose a danger to my wife?
