There was a thing years ago I think where a gay man donated blood and he had HIV and didn't know and they gave his blood to quite a lot of people who became infected with the HIV. If you've not had intercourse for 12+ months then you're fine.
I haven't looked into if I can, or even what blood type I am. Realistically I probably wouldn't donate blood, purely because of my major nausea when it comes to needles and blood.
Pretty much what Alkaz said.
Gay men supposedly have a higher risk of catching HIV and there are apparently rare chances that it won't be detected in tests, so it's outright banned if you've had intercourse (m>m) in the past 12 months.
Though it used to be a total ban until a few years back. 12 months is very lax compared to previous lifetime ban.
I mean, at present the USA has a total ban if you've ever had male-male sex, though it's changing this year.
http://en.wikipedia.org/wiki/Men_who...or_controversy shows all countries that allow it and dont allow it, a large number of them wont allow you to donate if you ever have m-m sex.
