Bienvenudo al foro y gracias por su pregunta. Su ingles es un poco atipico, pero mucho mejor que mi espanol!
You had low risk exposures, since oral sex carries little or no risk for HIV; and condoms work, so your anal sex exposures also carried little chance for HIV transmission. Congratulations for using safe sex practices!
The HIV blood tests are among the most accurate diagnostic tests for any medical condition. All tests of all generations are virtually 100% reliable at 6 weeks or more after the last possible exposure to HIV, and test results overrule all other factors, such as symptoms and exposure history. Your exposures were low risk our symptoms are not typical for a new HIV infection anyway. But even if they were, your test result shows you were not infected. To your specific questions:
1) The "3rd generation" ELISA tests are nearly 100% reliable at 6 weeks. See
http://www.medhelp.org/posts/show/1704700
2) Your symptoms are not typical of a new HIV infection, but this doesn't matter. The test result shows you were not infected. Something else is causing your symptoms.
3) Whether or not you have had HPV has no effect on your HIV test results.
4) Irrelevant. You do not have HIV.
5) No, you had a low risk exposure. See above.
I hope this has helped. Best wishes-- HHH, MD
