No, no. That’s the stiff upper lip part.
Is this thread contributing to the delinquency of a minor?
Well this certainly sounds arrousing.
Um, no. The penis does not, in fact, go past the cervix. Ever. However conducive this might be to conception.
Get thee a good anatomical drawing. It can in fact move past the cervix, depending on angle of attack (so to speak) it will move into the anterior or posterior fornix, if the man has enough length to get there. But I think you are meaning go INTO the cervix. And that does not happen. The cervix is a tightly closed ring of muscle, and it only softens and stretches to open in childbirth.
Must be why they call it “fornication”.
Actually, fornication is derived from the word fornix, which means “an arch”, which must be an euphemism for a brothel or prostitution. The fornix in the female reproductive system must be the “arch-like doorway” into the uterus.
Again, get a good anatomical drawing. It isn’t an “arch-like doorway into the uterus.” It is the area surrounding the outside if the cervix. It is also described as a cul de sac. It doesn’t lead anywhere.
Most. Romantic. Post. Ever.
Most erotic “dwarf” ever.
(A great setting for Science Fiction porno. A whole galaxy of possibilities!)
But if you really want a cluster-hump…
I’m not sure of the exact numbers, but you’re probably about right.
However, I think those numbers are pretty much irrelevant. Both penis and vagina are flexible enough that there is really no angle that would make penetration impossible. A position like reverse cowgirl, for example, has everything in all the wrong places based on those average angles and yet it is possible. (In fact, it’s a lot easier than you might expect).
As Pythagoras said, “the heat of the beat determines the angle of the dangle”
I thought the angle of the dangle was equal to the heat of the meat divided by the mass of the ass. Or:
AD = HM/MA
I feel as if I’m going to regret this, but my curiosity has been piqued: Umbridge, you sound like you’re a virgin. Are you young? Or have you just not gotten around to having sex yet?
OP needs to get a lab partner and start experimenting.
Hopefully he isn’t home schooled.
I am a life-long learner who is interested in many things under the sun - language, literature, arts, history, computer programming, biology, chemistry, physics, mathematics, etc. Reproduction is an important part of biology and what contributes to the definition of speciation. This thread is about human reproduction. Understandably, it is a sensitive topic and something that too many people take for granted. This thread simply illuminates what people do in their bedrooms.
From a biological perspective, copulation can be a costly business, and many animals compete amongst themselves for reproductive access. Humans mate differently, and there is this concept called “marriage”, which in Western culture, means the supposedly everlasting marriage between two persons. That said, I started this thread purely out of curiosity, not that I am really interested in it for my own practical use. 
That sure was a roundabout, drawn-out “yes”.
Not necessarily. Maybe his species does it differently.
It can be, if your bedding is made of rabbit fur and polyester. Better put a grounding strap on the bedpost.
Anyway… cardboard tube. I just thought I’d get that out of the way. Longtime members will know why.
