Question
Can a man’s penis enter a woman’s uterus?
Answer
Though a man’s penis may be long enough when erect to reach a woman’s uterus, it cannot enter the uterus. The entrance to the uterus is held nearly close by the cervix. The opening is large enough for sperm to swim through, but not nearly large enough for a man’s penis.
Only during delivery of a baby does the cervix expand. In the days just prior to delivery you will hear women speak of being so many centimeters dilated. What they are speaking about is how large the cervix has opened up for the birth of the baby. Generally, 10 centimeters indicates the baby is just about to be born.
