i was thinking if vaginas are average 3 to 4 inches in lengh, how come penises are average 6 inches....does that mean that the penis gets into the cervix too?
Very interesting question. :: First of all, the human vagina stretches out during sex. It's a very flexible organ. :: Secondly, during the coitus, the male penis does not always and not necessary penetrate very deep. Moreover, when two fat humans have sex, they have difficulty even penetrating each other; so in some cases, penetration is even impossible. :: Thirdly, now suppose you have a lover with a big schlong (say ten inches), and you're a petite woman with a small vagina (say 3 inches); your lover can penetrate the cervix, but he has to proceed very gently, because the muscle must be relaxed, so the woman must clearly be excited (if she's excited, the cervix muscle opens and closes in a rythmic movement, preparing to capture the semen); moreover, it only really works during menstruation, when the cervix is more open and loose. :: Fourth, some women love to have a penis penetrating their cervix during their menstruation period and going all the way into the womb, others can't stomach it; so it's a very subjective experience. :: Fifth, as a man with a monster schlong, I can tell you that the feeling of entering the womb past the cervix is a nice feeling, provided the muscle is loose enough and provided you're not turned off by making love to a bleeding woman; if it is, it feels like an elastic ring squeezing the glans, which is a very fine feeling (especially since the muscle is "ribbed" and there are cute "curls of flesh" surrounding it; it is also a very slimey affair down there, which is great); if the girl is not relaxed, it's nearly impossible to enter, and she will show you that it hurts :: Sixth, I would advice you to proceed very carefully, and test yourself first; masturbate a bit when you're having your periods, and bring in a dildo with a big knob; then see if you can get yourself to having the knob enter your womb. Good luck.
I know that even when just fingering a girl, I have been able to easily feel the cervix, and yeah, I'm talking about when the girl is in an "excited" state. So since my penis is significantly longer than my middle finger, it definitely hits the cervix, and that fact has been reported to me by sexual partners. I don't know about entering the uterus through the cervix, though! That info was new to me... -peacefuljeffrey
I know that many times when my husband is doing some deep penetration that it's quite painful and I'll actually cry out involuntarily. I can feel him just hitting my cervix and it's not too comfortable! I couldn't imagine what it would be like if he was any bigger. Ouch.
