Free STD tests
If you want to do it for free and anonymously, you go to AIDS Hilfe in Charlottenburg. They ask you for a donation for the quick tests (results after half an hour), but if you choose the laboratory one they might still ask for a donation, but do it for free as well if you choose so. And of course you have to go in person to get your anonymous test results. It's the easiest and cheapest way to keep your anonymity!
