For a small lady that's 132cm (4ft 6in) tall, yes. For a lady that's around 157cm (5ft 2in), they can have a 6in vaginal canal, and at 12, that's pushing against their diaphram, touching shy of their lower stomach. Remember, the penis doesn't actually go straight up and into the intestinal areas. The vaginal path is skewed slightly forward. That's why the ladies that like massive penises could show the penile penetration in the belly area. If the fetus, like penis, intrudes into the inner organ areas, the woman would be dying left and right during pregnancies.
