pessary too, though oddly, I knew that one.

Same (male) but only because it came up in the context of reading Wikipedia deep dives that led to court cases blocking their import[1] and the Hippocratic oath, which, oddly enough, prohibits administering them (along with abortion):

"Similarly I will not give to a woman a pessary to cause abortion."

Edit: But even then, I didn't know e.g. what they looked like, or anything about them specifically.
