Vaginal penetration by average size penis. (6 inches)

Penetration by an average penis (length 6 inch). When the erection is very hard, the penis will still give pressure and friction to one side of the vagina. It won't be able to directly stimulate the uterus and the back of the vagina however.

The heavy stimulation of a penis this large at the end of the vagina and at the vagina entrance may cause a woman to experience a uterine orgasm. Uterine orgasm occurs usually as a result of deep vaginal stimulation of the Epicenter (area at the back of the vagina). A uterine orgasm is marked by heavy contractions of the inner vagina and uterus that trigger a heat wave to run from the lower abdomen through the chest bone. Even more than in a vaginal orgasm, a woman has a sense of deep sexual satisfaction after this kind of orgasm.

The thickness of a penis this size also causes more vaginal satisfaction because the extra girth increases the friction and pressure on the vagina walls. The first few inches of these walls are packed with touch sensitive nerves. A thick penis enhances her pleasure also because it dilates the vagina and it gives more pressure and friction to the g-spot zone and the AFE Zone. 

Women usually like the feeling of being "open", the feeling of being filled by a thick penis. Women seem to like especially the "being pulled inside out" feeling they experience from a thick penis on the outwards stroke. The thicker the penis, the more the vagina walls cling to it and the more she will have such sensations.
