iwfuutaudls: Female Genital Anatomy 101
For the purpose of this short lecture, I will create a woman and a man. Their names, respectively, will be Emily and John.
Emily's vagina is 4 inches deep when she is completely un-aroused. As she becomes increasingly aroused, her vaginal tissue is engorged with blood. Once she has reached full arousal, Emily's vagina is 7 inches deep and has finished growing inward.
Her boyfriend, John, has a dick which is 5 inches long when completely un-aroused and 8 inches long when fully aroused. He carefully inserts his fully aroused dick into Emily's fully aroused vagina. As he bottoms out in her, he still has 1 inch left to fit inside of her. Therefore he slowly pushes into her, causing the end of her vagina to be stretched into her. He feels the tightness, the pressure, and small ridges against the head of his dick. Emily feels the push, the stretch, and something clearly moving as a direct result of his push. If the push is gentle, Emily will enjoy this sensation. Both her and John believe he is pushing or pressing into her cervix gently. They are both WRONG.
In fact, John had passed Emily's cervix before even pressuring the last inch of his dick in her. What John and Emily do not know is that, as her vagina grows inside of her, Emily's cervix moves and shifts to a position which is slightly back but more-so further up (towards the outside of her stomach) than its position when Emily was not aroused at all.
The ridges that John is feeling and the "cervix" which Emily feels being moved by him are, in fact, a net of soft cartiledge which holds up Emily's intestines. John has this same tissue in his body, holding up his intestines.
The only true contact that John's dick is having with Emily's cervix is the friction which occurs as John slides his dick past it when pulling out and diving into her vagina. The sensation which Emily perceives from this friction is almost identical and is therefore blended by her brain with the sensations of him sliding past her entrance (the wings of her clitoris), past her g-spot (the tail of her clitoris), and past smaller sensory areas which are located along the inner-lines of her pelvis.
If John truly wanted to push and to pressure Emily's cervix directly with the head of his dick, he would have to penetrate her at an extreme angle. For example, Emily would kneel down on the floor and rest her chest on a chair, arch her back downward as much as possible, and close her legs together. John would have to stand behind her and squat down so that his feet were still "standing" on the floor. John would then need to rest his chest on her shoulders, and keeping his dick fully hard, penetrate Emily's vagina at a somewhat perpendicular angle relative to the floor. This would cause John's dick to directly hit into Emily's g-spot, he would then adjust his angle so that it was a diagonal but still steep-sloped, and he would hit behind her g-spot, namely, her cervix. It can be done, but Emily would not want it.
