Well, that's a tough situation when your country makes you too scared to test for things because of the consequences. What about a vacation to somewhere safe to test? Can you have an oraquick home test mailed to you? You can then test on your own. But honestly, with a one time exposure years ago, I would not fear HIV. One time exposures are rare to actually transmit the virus. And all circumstances have to be in place. I would try to forget it, get an oraquick test or take a vacation to somewhere you want to visit that you can also hop to a clinic and get a quick test.
You do not need to get in touch with old partners. You can certainly take an HIV test at any time as a routine test. However, I would certainly doubt you have HIV 7 years later. Do jump on the anxiety train.
