Maybe I can help shed a little light on the bigger picture -- as a regular donor - I've donated 9 Gals of whole blood, one pint at a time, and switched to apheresis in Sept at their request - they can get 3 units of platelets from me every week or two instead of 1 unit every 8 weeks. If you donate red blood cells, it takes 8 weeks to rebuild your supply. My cardiologist and I discussed it - I was on Plavix - we agreed I could go off it. Also off aspirin 72 hours before donating.(platelets)
There are several questions about sexual activity, as well as travel abroad, exposure to diseases, meds you might be on. Man on Man sex is only one question of many. They have to screen out all people w/ possible issues. The blood tests, while good, aren't 100%, so they can't just screen your blood by the test and go for it. They rely on people being honest.
Are you feeling well today?
Have/ever had a bleeding disorder?
Have/ever had a heart problem (e.g. Heart Attack, Angioplasty) - if at least 6 mos since and ok'd by doc, you can donate - as long as meet drug deferral period issues.
Have you ever had sex with someone who has taken drugs not prescribed by a doctor by needle? (or have you taken drugs by needle not Rx by Doc . . .)
Ever been to Africa or had sex with someone from Africa?
If you are a male have you ever had sex, even once, with another male since 1977.

Human Growth Hormone, Insulin from Beef, dura matter transplant, surgery in past . . . including oral surgery.
Currently taking anti-biotics for an infection? (OK if you're taking a maintenance anti-biotic to prevent an issue and your currently symptom free - e.g. my daughter had Kidney "backsplash" when she was younger, was susceptible to urinary tract infections, so they put her on a maintenance anti-biotic for several years while they waited to see if she would outgrow the condition, or need surgery to correct. She outgrew it.

Immunizations in the past month . . . Flu is OK.
Time abroad in UK, a lot of other places in Europe that add up to 6 mos or more in the period 80--96? or similar.
Plavix, Warfarin, Heparin, Tegison, other drugs that affect the blood itself. Meds have a deferral period from a week or two to more.
Donate whole blood, platelets, plasma in past 8 weeks - I answer yes, then platelets and last donation 7-14 days ago OK. double reds past 16 weeks?
Served in the military/been a dependent of someone in military and been in . . .
Yes, it all stems from way back then - also why it's supposed to be illegal to sell your blood, anymore. Guess not in all states, based on post above. They used to process in large batches for economies of scale - then they discovered they ruined a lot of blood -- have gone to single lot, single use needle donations/processing.
I don't believe the regs are the Red Crosses, I believe they come from the NIH or FDA -- which oversees blood products like other prescription medications. They are required to ask the questions to try to make sure the blood supply is as safe as humanly possible. Yes, it costs them a lot of potential donors. They HAVE revised SOME of the rules - notably the UK/European travel time frames.
Our local regional center was fined $6M several years ago - apparently due to paperwork controls. It had nothing to do with the way they handled the blood, itself. They are very serious. You also have to have an iron level of 12.5 (mm hg?) or greater to make sure your aren't anemic.
Oh, yeah, hemophilia?
Been in Juvenile or regular detention center for more than 24 hours?
Had a tatoo in past year?
Accidental Needle Stick?
Come in contact with someone else's blood?
So, it's not just gay men who have been sexually active that they are screening out. There are a lot of other people in the same boat. The goal is to ensure safe blood. I'm sorry they haven't come up with a way to be more inclusive, too, but again, I sincerely think the regs came down from the Fed.
