Hi, several months ago I had protected sex with someone I didn't really know. I had unprotected oral sex for several minutes (I am female and was performing the oral) with this person but there was no ejaculation. I was tested via vaginal swab and was negative for chlamydia and gonorrhea, but failed to think that I could have contracted something orally. I have had no symptoms in my throat, however my tonsils have been swollen slightly along either side of my neck for some time (I had them checked and my Dr. was not concerned). My question is- what are the odds that I could have contracted an STD from this encounter, and could the swollen lymph nodes be an indication? Again, there are no other symptoms. I also do not have tonsils if this makes any difference. Thank you
