I am a male and recently received unprotected oral sex two weeks ago. The woman claimed to not have any STDs, and had no visible signs of infection. I had tremendous anxiety over this encounter, so 3 days later went for testing. Both my urine and blood tests came back completely negative for all STDs, and my doctor told me I have nothing to worry about. However, I have had a few symptoms which are giving me anxiety, namely: slight sensitivity/burning on head of penis, frequent urination, occasional cloudy/white discharge in urine (may be semen?), and a sore throat which i believe is unrelated. I have no visible signs of an STD (sores, lesions, rash etc) but am extremely paranoid about the symptoms described above. Is testing 3 days after too soon for reliable results? What STDs does it sound like I am at risk for/may be experiencing, or is this simply my own anxiety getting the best of me??
