I don't think I should have to sign up for any STI passport because people sleeze about. Like what, oh seems here you've recently toured Scottland, Virginias Beav, Barry's Bridge, Carls Chasm, Betty's bluffs or hiked Arizona's hoodoos. Oh, and then im going to share that with everyone i have sex with. That'll fly well I'm sure. Next stop: judgement and predisposition land. I don't sleeze about, I do my homework, and like most responsible adults, would definitely not be sleepy around if I had knowledge that I did contract some sort filth from, what I am assuming was a grossly casual hookup. And guess what?! If you have to wonder if this person may give you a sexually transmitted disease maybe ask yourself if sleeping with them is a really great idea...this is like saying my car insurance premiums are going up by 200% because everyone on the road drives like assholes. Ridiculous. Be responsible. Use some form of protection, like they told ya in grade school if you are concerned that you have a chance of getting the clap from a candid partner.
