Ok so on october 2015, im a male and had a one time encounter with another male of unknown status, but i dont think he ever penetrated me it was more like poking/rubbing aggresively and at about 2 weeks after the incident i felt swollen neck glands which i never felt before. I got a HIV 4 th generation test done at 6 weeks after the incident and it came out negative. Now its been about 6 months and im starting to feel the swollen neck glands again might i have been infected with hiv?
