Few other STIs are transmitted through receipt of oral sex.  In the absence of oral sores or lesions there is virtually no risk for syphilis.  Similarly, chlamydia is almost never present in the mouth and when it is, transmission almost never occurs.  Gonorrhea can be present in the throat and can be transmitted both through the performance of oral sex or, very rarely, through kissing.  Since most gonorrhea is symptomatic, this too suggests that you did not get gonorrhea from the expsoure you have described.  Your symptoms are not particualrlry suggestive of any STI.  

In response to your specific questions:

My final questions are

1) after 29 days with low risk exposure and results showing negative. Should i move forward and forget about the situation or should i still test after 6 weeks.

2) i will be having knee surgery in 2 weeks and just for general information. What are the risks of disease such as Hiv if i am to receive a tendon from a donor from a bone bank. Ie. I am getting a ligament from a cadaver? Thank you

2.  Human materials that are transplanted into other persons, including tendons only come from person who have already been tested for HIV and other potential infections. There is no risk from the situation you describe.

I hope this information has been helpful to you. EWH.
