Unfortunately it applies to gay men only. Our straight counterparts can switch up partners as much as they want.
Well, it’d apply to bisexual men who’ve had male partners as well.
I should also point out it doesn’t have to be new partners. Just if you’ve had more than one partner you can’t donate even if it’s an exclusive polygamous relationship.
I see what you’re saying but they are specifically worried about anal sex. You’re welcome to switch up partners as much as you want as long as anal sex isn’t involved, which is much more likely and much easier for the heterosexual community.
Same goes with prep. I’m sure that there are circumstances that would have individuals taking it that are not related to their sexual orientation.
I’m just pointing out that despite the major improvement it still excludes gay men quite thoroughly from donating blood.
