Ah yes, the first time you reach your hand into a girls pants expecting to find things where your penis is… and you get nothing, and you try to play it off casually but in your mind your freaking out thinking she’s a real life Barbie doll.

So true. I had some real surprises when I first got to explore the anatomy of an actual girl, despite having had reasonably good sex ed in school. Not that I got my information from hentai though, that just wasn't a thing at the time.

First time I fingered a girl I felt like Colombus. Really thought I'd hit the new world much sooner.

Yep, basically an inch from the anus.

This appears to be a common one. I've heard this elsewhere too

Yep, I used to think that vaginas were exactly the same height (proportionally) as the penis, such that intercourse could technically be achieved by walking straight towards eachother with the penis held high. It cerainly was an interesting exploration the first time I attempted to find my way.

The target audience of that type of shit generally won’t ever know the difference.

Its sort of similar with your ass. Its always portrayed as "s-shaped" sorta and/or sideways (like a tailpipe on a car) when its...sorta more...south originating and facing than fhat...ya

Are you referring more to the Mons Pubis or something, like the "vagina mountain" thing?
