There wouldn’t be any blood.
Look, I’m just trying to get facts. There is no way to screen blood for behavior. The blood supply is safe. This seems to be a silly issue.
I am at 103 donations, and I don’t do anal sex, so we have at least one donnor left.
The blood supply IS safe as long as we keep in place screening criteria as we now have. What makes you think the level of safety will remain static once prohibitions to unacceptably risky behavior are lifted?
