I gave oral without condom?!! ?

As said by the previous answerer the chance is severly slim, especially because you said he did not ejaculate (not that that would have mattered much) In order for you to get HIV from giving oral sex you would have to have either a cut in your mouth at the time capable of allowing the HIV Virus into your blood stream or (as I was once told by a member of the ALFA Orginization) you'd have to swallow a gallon of ejeculation. (Which I hope, is not typical >.<)
