odd sex questions that starts with some sort of complaint about previous threads (edited title)

And all this time we thought he was a MARTIAL arts instructor; nope, he’s a MARITAL arts instructor.

it doesn’t really. The male on top in that position is supporting most of his weight with extremities if he’s at all interested in the well being and pleasure of his partner (or is completely selfish and simply wants repeat business or referral. :D) Hips are not necessarily in contact for good chunks of the motion and aren’t a major source of support.

Are we allowed to offer suggested titles? How about “Further questions about sexual intercourse and pelvic thrusting, with special attention paid to acrobatic maneuvers before, during and after coitus. Side discussion on the risks of penile fracture, both in humans and other mammals.”

I think that can be more succinctly expressed by “Another Thread by Umbridge

What’s the impact factor of the SDMB journal?

“Sheldon Cooper is curious”

If you read the Wikipedia article on penile fracture, then it is actually cited that the most common causes of it are vaginal intercourse and aggressive masturbation. Of vaginal intercourse, women-on-top positions pose the greatest risk, while the missionary position poses the least risk. The missionary position may not be ideal, if the woman has an intact hymen, and the tearing or stretching of the hymen may cause pain. Add in the extra weight, and the woman would be locked into that position. Eh… Who says sex must be easy?

Human estrus actually exists. It’s just that women are largely unaware of it. I once heard a lecture that mentioned the lack of knowledge of one’s own estrus and how that would lead women to appear like they are in estrus ALL the time. A female dog, a bitch, that is in estrus is called “in heat”, and it looks crazy. I wouldn’t be surprised if that is how the word “bitch” loosely means “crazy woman”.

IIRC, the number for successful fertilization is much higher than 20%. Take a look at unprotected sex rates, and you’ll see why. Even if a couple has 20% chance of fertilization, then they probably would have to have sex every night. The woman may not know that she is pregnant up to the third month of pregnancy, so if such a woman is trying for pregnancy, she must abstain from alcohol, stay fit, eat healthy, and have sex every night to make sure the conditions are ideal for fetal development.

:smack:

You know what I hate about watermelons? They’re so heavy that their own weight squeezes all of the water out and so they’re all rubbery and dry like an old sponge.

And it’s a fact that clouds are heavier than a 747 airplane. So if a cloud was over you there should be a change in air pressure, and that would make your ears pop.

I don’t what to say man. If you’re going to continue extrapolating wrong from wrong, there’s not a lot we can do to help.

You’re talking to a bunch of people who have had sex, and we’re telling you the woman is not locked into that position. We don’t need to hypothesize – we’ve done it. There’s no “the woman would be…” – we know that she’s not, because we’ve done it. Most of the time, both partners in missionary-position sex are thrusting back at each other, and the woman is not bearing the bodyweight of the man.

I have a feeling that the members here are focused on recreational intercourse, while I am mainly focused on procreational intercourse. Somehow, there is a close association between intercourse and pleasure that many people find difficult to separate. The close association and the uncertainty of fertilization make me think that perhaps it’s best to not think about sex as a means to reproduce, but sex as a means to have fun in order to reproduce.

For the love of God, man, WHY?

Do go on… We’re dying to hear how it’s so different.

(It’s not like anyone ever got unintentionally preggers from recreation sex, after all!)

There’s no difference, but you of course know that. :rolleyes:

For most people there’s no difference.

Since recreational sex is often portrayed to involve sexual attraction, and many marriages may be arranged or set up by parents who really analyze the partners’ characteristics and compatibility, and the fact that gays and lesbians can produce babies, sexual attraction in traditional arranged marriages or semi-arranged marriages is not emphasized that much. Commitment is far more important. This suggests that sexual attraction and therefore recreational sex are not necessary at all in reproduction. Yet, sexual pleasure really is intertwined with sex, making the idea of a person who is not sexually attracted to his or her marriage partner complex. I think sex is more complex than it seems. I find it difficult to imagine why one would engage in sex for pleasure alone, if he or she is not attracted to the partner. It’d make more sense to have sex to reproduce to continue the family line.

This is correct.

The hymen is vestigial, it tears once. After it tears, it shrivels, atrophies, and becomes not a concern. After that point, the moment of insertion becomes very enjoyable for the woman due to the clittoral body that closely surrounds the vaginal orifice – in fact, it is fun to … ahem, nevermind about that.

I believe it was Kinsey’s wife who had difficulty with her hymen (at least, that seemed to be what was being hinted at in the movie). To deal with such a problem, it is possible to tear the hymen and let it heal in advance of having sex, so that the woman can have a painless deflowering. Some men get a particular thrill from tearing the hymen with their penis, but I kind of think causing ones partner a lot of initial pain is mostly not desirable (at least, until both decide how much pain they, umm, again, nevermind about that.

When a man climbs on top of a woman, she usually wants him to and usually does not feel locked in. Often, the initial insertion calls for a little guidance on her part, unless she is already very wet from, umm, linguistics or other foreplay that arouses her a great deal. More importantly, when you consider the thrusting activity, most women have enough mobility even underneath a man that she can move to eject his penis in the back-stroke, if she feels so inclined. In addition, both partners have these “mouth” things which they can and do use to say these “word” things to each other, like “that doesn’t feel very good.”

Well, I did not say “fertilization”, I said, “viable conception”. Actual fertilization occurs rather often, but many of those zygotes either fail to implant or simply expire some while after implantation. It has been suggested that, for many women, what seems to be a difficult period is very likely an early miscarriage. Statistically, the average viable conception rate for unprotected sex, meaning a pregnancy progressing beyond the second trimester, is around one in five. Hence, sex must be a social activity, because we have to do it a fair bit to get babies.

Got any hobbies?

Umbridge is weird. Rhymer-level weird. In fact, he isweirder than me.

That does not happen often. It’s kinda scary.

Are you sure Umbridge is a male? What would you do if you found out that Umbridge is a she? Propose?
