Blood donation question

[NetWareHead]

Hope this is the right forum, didnt want to post in off-topic.

I went to donate blood for the first time at a Red Cross center. Needed a bit more time to establish me as a member, do some tests and get entered into the system. The nurse working my account explained a few rules and then we went over the disqualifications that would make you ineligible to donate blood. This one in particular stood out to me:

"Had a blood transfusion, ear/skin piercing, accidental needle stick, or come in contact with someone else’s blood in the past 12 months. (Ear/skin piercing procedures may be acceptable depending on the technique used.)"

The first thing that came to mind was sexual contact. My fiance and I have had sex on her period (no condom) which I beleive would have disqualified me. So I mentioned it and the nurse gave me a handwave and said that didnt matter. She let the donation proceed and all went well.

Did she break a rule or is something like this not a cause for worry? Wondering why I was allowed to donate in spite of these published guidelines.

Come in contact with is a loose term. They're concerned about blood entering your bloodstream, which is fairly difficult with sex as you describe unless you're cut/lacerated/etc. She probably should have asked more questions but she probably wanted to get over the topic as quickly as possible haha.
