I have a friend who lived with a bi-sexual man for a year after which they broke up. He was faithful to her during that time.

My friend had given blood since she was in her teens but was no longer allowed to do so after being with this guy. One of the questions on the form the blood bank had her fill out asked whether or not a potential donor had been with a gay person. My friend answered "yes" to this and was told she would never be allowed to give blood again because of the possibility of her having gotten HIV from him.

Sort of guilt by association. She was more than willing to be tested for HIV but the people at the blood bank told her it wouldn't make a difference.

I guess they think they are being super careful but I think this was a bit excessive.
