So, what’s the truth? Is it possible for a man to poke the baby in the head with the tip of his penis while he’s having sex with his partner or wife? Before we tell you if the answer is– “yes” or “no,” first, a brief anatomy lesson.The growing baby is floating inside a sac of amniotic fluid which is floating inside the amniotic sac inside the uterus. The ultrasound picture above is of an actual penis inside a woman who is 6 months pregnant. The white colored area above the penis is the cervix. Beyond that is the uterus, amniotic sac and baby. As you can see, the direction of the penis is down. During sex, the penis fits in a space underneath the cervix and uterus. So, what’s the answer? Can you poke the baby in the head during sex with the tip of the penis? No. It’s not possible, because the baby is protected behind the rigid cervix, uterus, and amniotic fluid. ALTHOUGH… It is possible to “jostle” the baby. Wait. What? Yes. It’s possible for a man, regardless of his penis’ length, to gently jostle or push the baby. However… It’s no more of a jostle than the baby would experience if the pregnant woman were to run up a set of stairs or to exercise. As you can see from the photo, it’s quite possible for the shaft of the penis to “brush up against” the cervix, which could, in turn, “jostle” the contents of the amniotic sac… and thus, “jostle” the growing baby The uterus is protected by the cervix, a rigid barrier to the vagina which slowly opens over the course of the pregnancy. The birth canal is 3 to 7 inches in length, depending on the woman’s state of arousal.
