first of all you cannot presume because you had a test three months ago that you are HIV negative....there are window periods in which the virus does not show up in the test...if you are still worried get tested again and if you are going to have multiple partners you will need to be tested regulary for not only HIV but hepB, and C which is easier to catch then HIV...also the other sexually transmitted disease women and men forget about like chlamydia,human pappiloma or the older scourges of mankind that still plague us Gonnorea and Syphilis   These are very dangerous and some can be caught through oral sex as well...But people have been so worried about HIV they forgot about they others and have fallen prey to them in the MLLIONS!!!  PS keep up regular doc visits ,sleep only with people who have also been tested for a host of illness's and protect yourself in all your orifices until you find a stable partner...
