You're OK: Oral sex is safe sex for HIV, with no proved transmissions by fellatio from mouth to penis, only rare ones penis to oral. You didn't need testing on account of this event and for sure not the multiple expensive ones you had. But the results from that combination of tests are conclusive. For sure you didn't catch HIV during that exposure and no further testing is needed. Best wishes and stay safe! ...Read more

Polymerase Chain Reaction (Definition)

Polymerase chain reaction is a method of finding a specific piece of dna and copying it over and over again until there is enough to study. The technique allows a scientist to detect very small amounts of dna in a swab sample then reproduce enough of it to study it. It is very sensisitive for detecting the presence of certain bacteria and is also used in doing other ...Read more

There are lots of ways to have safe sex-b careful ...Read more
