Just discovered these rule changes based on your comment. Unfortunately my partner and I still can't donate blood (they're on PREP, and I was in a vaccine trial that disqualifies me), but it's cool that they've finally eliminated the worst of the queerphobia in the US.
I experienced the reverse of you - as soon as I transitioned I was disqualified as a trans man who has sex with men, even if the sex was identical pre- and post-transition. These were the previous "updated" rules that were supposed to be less queerphobic, but obviously weren't hitting the mark.
