It's never a guarantee that if you have sex with an infected person, that you yourself would get infected. When having sex with an infected person, you can become infected the very first time you have sex with them, OR you can have sex 100 times with them and never get infected. The thing to remember is that the more times that you're exposed, the greater your risk becomes. But it's never a guarantee that you'll get infected. If the HIV virus doesn't get into your bloodstream, you won't get the infection.
Some people take greater risks than others, and some people are simply luckier than others.
So in your case, if its been more than 6 months after your last possible exposure to the virus, and you have not been re-exposed since then, there is no need for you to get tested again.
