Was just looking at the guidelines for giving blood and it reads that you must not give blood if you have had sex with:
A man (if you?re a male). Men who have had anal or oral sex with another man (with or without a condom) are deferred from blood donation for 12 months.
Can someone explain to me why this is different from heterosexual anal sex or any sexuality oral sex?
I don't see why the risk is greater.
