I know that there have been stories similar to this one (which is rather depressing), but I decided immediately to submit it because of how he kept going.
It was 1 AM on a school night and I was hanging out in a study room in my dorm with a mixed group of friends. We were becoming increasingly crazy, so the conversation was centered around things like childbirth and genitalia, naturally. At some point, the fact that females have three holes came up, and one male friend told us that we only have two, because the urethra joins the vagina or something. We explained how it works (which we shouldn’t have to do with a science major, or any other adult) and pointed out that we would sort of know just from living, but he wasn’t having it. He was on his laptop, so he proceeded to pull up a diagram. We pointed to the urethra, but he insisted that it was an “opening,” not a “hole.” We asked how an opening for urine could exist without a hole, and he explained that our inability to agree on the subject was due to the fact that “We have different definitions of a hole.”
