You need a urethral swab(chlamidia,micoplasma,ureaplasma) although the general consensus on bacterial transfer is that you need to have penetrative sex on rare occasions it has been recorded that it can be transferred thru oral sex especially deep throat, so get the test, get the correct treatment(if positive) and next time stick your junk where it belongs inside the vagina not the throat.
All the best to you.
