The one where your penis is in her vagina.
Oh, now you’re just restricting yourself. Besides, you don’t want the other orifices to feel left out, do you?
Bonobos will mate every chance they get in every position they can get.
[spoiler] Here’s an NSFW image of hot monkey love in the missionary position.
Here’s the entire article, including the picture.

Including having one’s knees clamped together, carefully holding a single aspirin there. :rolleyes:
Mebbe if you ingested the aspirin, the headache would go away & then the knees wouldn’t need to remain clamped together. 
In case you can’t be bothered to look at this article I’ll give you a quote from it:
That itself is a reference to * Vanessa Wood’s book Bonobo Handshake*
This issue was addressed in Quest For Fire, where it was opined that the missionary position is what separates us from the apes.
Most natural position?
I thought it was sitting, in front of your computer monitor.
The first Book of Lists (circa 1979, edited by Wallace, Wallace, and Wallechinsky) included a list (created by some scientist) of positions, which were assessed by “likelihood of pregnancy.” This speaks directly to the OP’s concern with anatomy. I recall that “man on top” (missionary) and “rear entry” were the only ones in the highest category of likelihood – but neither was higher than the other. (Surely there has been more research on this since 1979).
That has just made my day!
She looks so bored, as if she’s lying back and “thinking of England/Africa”.
Well that’s an authoritative source!
And use sex as a conflict resolution mechanism. Upset ? Eh, fuck it.

Ninja’d by Tom Tildrum! If I recall correctly QFF also featured the first BJ. Well, not really. Rae Dawn Chong was from the more advanced “tribe” and serviced the male questing for fire, much to his surprise. Between that and the new missionary position he was quite flummoxed.
Just about everybody I’ve ever been intimate with had all kinds of different shapes of all their parts, most preference is cultural but if you’re a quick study you ought to find what works best with whatever you’re with. I’d say, most people need to give doggy a rest, it’s a big world out there…
My wife has a definite preference to the angle in the missionary position. I’ve yet to measure it but I know when I get it right!
This seems like it would be ridiculously easy to test this using a paper towel tube.
Or me. I volunteer.
The answers, it seems to me, depend on the goal in the lovely act. If it’s conception, that’s already been answered.
If the goal is pleasure, and if Graffenberg is correct about the G-spot, the couple might narrow it down to the most pressure and movement on that spot. The male is less picky about positions
Diagrams of the angle of the vagina abound, from the back of a tampon box to Masters and Johnson books and sex toy catalogs. Keep in mind that the vagina, and the rectum next door, will readily adapt to angles other than the “at-rest” position the diagrams show.
Nice username/post combo!
That got a chuckle from her.
