I also knew girls in college that had no idea women have separate orifices for reproduction and bladder.
did you mean orifice or organ? Because the two organs are accessed through the same orifice
Ah - Mom told me a horror story about a young woman who had NOT ever seen a doctor before getting married...finally came in after her honeymoon in real pain. She'd been told that things would be painful at first, when her hymen broke - but would not be painful after that.
Her hymen was unusually thick with a couple of tiny holes in it (so she'd been menstruating) but apparently she made it into the medical books (or at least that doctor's anec-data files) because it was also still intact...and what should have been an almost unnoticeable and slightly in front of the other opening was enlarged, inflamed, and....well...
The doctor got a scapel & cut the hymen, used a small mirror to show her where her lady parts were, and instructed her to tell her new husband that they needed to wait a few days for the inflammation to go down - then she needed to make sure that he got the right orifice....
OW. OW OW OW OW OW. OW!
Did she not get a UTI? Oh, and OW.
Oh my gosh, that's awful.
When I was little, my grandmother had early onset dementia and my grandfather was telling about having to help with her tampons and such (why he was telling this to a six year old, I have no idea). Anyway, my mom was a scientist and was really big on appropriate names for organs (instead of cutesy terms like wee wee or whatever), and so even at 6 I knew all of the parts of the body pretty well. My grandfather said something about not understanding why the tampon didn't stop her from wetting her pants, and according to my mom I looked at him and said, "Are you stupid? They're different holes." Apparently at 6 I wasn't as concerned with etiquette as I was with being right. 
I have no idea - but the story was told to me roughly twenty years ago and was supposed to have happened more than twenty years before that - so maybe they got lucky about not carrying them?
Or maybe the week of rest was for more than just allowing the hymen to heal and the urethra to shrink to a more normal size?
I have to admit that I squeezed my thighs & knees together tightly when I heard that story for the first time....

Next story - from a college instructor - dated in the very early days of fertility treatment - so at least fifty years ago if not longer. He'd heard these from one of his professors who worked in the field when it was younger.
A doctor and his wife were in for diagnosis as to why they had never had a pregnancy. After checking to make sure that they were doing the appropriate deeds (don't laugh - apparently one very religious couple was praying about getting pregnant but weren't doing anything BUT praying - things worked out well once they were told of other activities with a higher success rate on getting pregnant AND that it was okay to do THAT since they were married and doing it for the purpose of having a baby - did I mention that they were apparently very, very religious). I was a preacher's kid and could believe that one...lots of preaching about the "sins" of lust & fornication without a lot of preaching on the joys of marriage...it could happen. Although they had to have had very low s3x drives....
The one that flabbered my ghast was the second story. The doctor and his wife....checking the male is always easier, a sample jar, a little time alone, and a microscope - yep, they are present, numerous, formed normally, and active....
On to the more difficult female checks - where they noted that she had no body hair. She didn't shave. Her external organs appeared fairly normal but they couldn't find ovaries, a uterus, or other equipment that they expected.
What they did find was a "blind opening" (I think it's called) and...undescended testicles. "She" was a pseudo-hermaphrodite - something so rare that a medically trained person hadn't recognized that he was married to one.
Rather than blow up the marriage by telling them that "she" was genetically male but apparently did not react to testosterone at all - they were told to adopt, as her "female organs" were incapable of supporting a viable pregnancy. But it did make it into the medical books years later AND certainly the anecdata banks on "odd things we found people doing or not doing before coming to the fertility clinic".
