I can't be alone in being lost when trying to determine sex positions.
Sometimes I will go to wiki page, scroll through examples, and say "yes, something like this one, but with x partner flipped". But won't find the position that I'm looking for.
I started adding "same but if x was different" (anvil position, arch position, bent spoon position, bodyguard position, jockey position so far).
Finding similar positions is kind of hard though, and I'm not sure if my idea even makes sense.
