Hi there -
This isn't going to be from gonorrhea or chlamydia if all she did was use saliva as a lube. (I'm guessing that's what she did - you said she licked her tongue and that doesn't make sense to me).
Your testicles may hurt from not wearing enough support, or from something else, but have you talked to your doctor about this?
No not yet i will book an apointment?
because i tested for both gonorhea and chlamdia and were both negative
maybe do i have to do a culture?
i mite be another common bacteria
You need to see your doctor. We can't tell you what it is exactly.
could it be dangerous if anything?
No, you just got a blowjob and a handjob. No risk for anything dangerous from either of those.
The only risk from oral would be gonorrhea, NGU or syphilis. Syphilis wouldn't give you these symptoms, and you are negative for gonorrhea and NGU.
