8 XXX : ConfusedBoners

There should be a sub for educational NSFW images like this one. Or perhaps there's one already and I just don't know it yet?
What kind of Bingo card is this?
This is not confused boner worthy, what the fuck is wrong with you OP? -_-
Fantastic. Ive been looking for a good Vagina Comparison like this for my drawings. (Trying to go NSFW sorta.)
lowleg wtf
What's the difference between the "hairpin" and "W" types?
The vaginas look pretty much the same. None of them have a visible clit or large inner/outer labia. The main differences are the size, shape, and angle of the pelvis and what angle the torso is facing towards the viewer. For example, 4 type looks it's at a 3/4 view rather than straight forward like the others, and to see the butt cheeks like Low Leg type has, you usually have to look from a lower angle. That or she's really skinny and had butt cheek implants.
I need one with real humans. For scientific reasons
TIl what I've got is called Catenary.
