You are correct.

@Ferrotter  
Yeah, it’s anatomically incorrect.

@Ferrotter  
wow finally someone else who really knows of equine anatomy too

Glad that I am not into fanatic level of anatomy correct technicolor cartoon horses to ruin my fun of fapping on them.

@Ferrotter  
OP’s point was:  
If you draw vaginas like top-right(which a lot of artists do), fuck them like bottom-right.

@ColgateFIM  
No. Primates are extreme outliers among mammals in female genital anatomy. The layout in a pony is not like this. This is primate anatomy stuck on a pony.
 
On a pony, the entire opening of the lips (and there is only one pair of lips, not inner and outer pairs; double lips exist only in primates) leads into the vagina, not just the upper end. In a pony, the clitoris lies on the floor of the vaginal tube a couple inches in. Not at the bottom of a flat portion. And the urethral meatus is also on the floor of the vagina, somewhat deeper inside behind the clitoris. That’s normal mammalian anatomy. It’s one (fairly) straight tube. The “where” on a pony is “anywhere inside the tube.”

Thanks, that’s very useful! I feel a bit weird not saving this to my porn folder, but oh well.

@Ferrotter  
it is penetration anatomy, as in, “WHERE” not “HOW” =D Everybody draws vaginas differently, but the basic layout should generally be the same

What a6p said. This is not correct for a pony.

@TexasUberAlles  
It’s a vagina tutorial hoihoihoi

@Nightweaver20xx  
Well, I’ve been married for fifteen years, but not to a horse.
 
…There’s a horse right outside, though, so yeah– those teats are too far back.

I’d like to have sex-ed with ponies…  
Oh yes, I’d totally would…

In depth discussion of colorful pony genitalia.  
Sometimes I don’t know whether to laugh or cry.

@a6p  
It’s more of a basic oversight than a deep-dive into advanced mare genitalia

This isn’t actually anatomically correct. Mares have internal urethral openings and clitorises, so nether should normally be visible.  
Women and mares are different in this respect. During vaginal intercourse between humans, the penis can only indirectly stimulate the clitoris (through the pelvis). During intercourse between a stallion and mare, the clitoris is usually directly stimulated by the penis.

Nice guide.
 
Wait, I mean  
pfft. Marshmallow pony can be fucked anywhere.

@suddensharpintakeofbreath  
This. This is my fetish.

This is about drawings of cartoon ponies having various types of sexual intercourse. “Reality” is a far, far away concept at this point.

Penile fracture is an actual thing.

Who cares about realism? Fuck that urethra anyway!

The more you know…!

@Nightweaver20xx  
I’m not a virgin. Though I often feel like one.
 
And that’s not a Madonna joke.

That we NEED something like this in this fandom speaks to something… different about us.
 
I’m not sure what I’m trying to say, but I think it has something to do with us all being virgins and not knowing what a real pussy looks like.

It’s always nice to see some people care for anatomical correctness.
