Answer to the first post (too lazy to copy and paste)
When it comes to testing for HIV, I definitely wouldn't do it for myself... I know you can live much longer when you have treatment but I think I'd prefer to live in blissful ignorance until I got AIDS. But one thing I would never, ever be able to live with is knowing that I'd given the disease to someone else... Especially if it was someone I cared about. So, in my opinion, everybody who might have been exposed to HIV should get tested, no matter how small the chances are... it's the only way to get rid of the disease.
Fuck, what is the world coming too?
