Exchanging Papers

[jizzybelly.livejournal.com]

I have seen people posting here about "exchanging papers" with their partners before having sex. I gather that this means exchanging medical records. It seems to me that this might be a good idea in theory, but not very practicable. What's the best way to do this, for the purposes of preventing STDs? How would you bring this up with your partner, and what should you ask your doctor to be tested for? Then, how would you get copies of all the test results? Just ask the doctor for them? I guess I need instructions... Thanks. :>
