Talk:Vaginal sex

We should be careful what we say here. For example, activities such as the use of vaginal sex toys will not (of themselves) cause pregnancy; on the other hand many non-vaginal sex acts involving potential contact with sperm, even in small amounts, can cause pregnancy if care is not taken. -- The Anome 01:02, 27 Oct 2004 (UTC)

Inaccuracy of the "gliding action" image

The "gliding action" image appears to be seriously inaccurate, as it does not show the most dramatic anatomical feature of coition, namely the penis bending during vaginal insertion. Actual NMR imaging of sexual intercourse shows that the penis bends into a rather surprising boomerang shape inside the vagina. See [1] for a comparison of previous visualizations of sexual intercourse with actual NMR images of coition.

Given that this major feature is completely missing in the image makes me wonder about the accuracy of the more minor features in the image, and what, if any, actual evidence was used as a basis for creating the image. Comparison of the image above with the NMR images shows that it is mostly a work of imagination.

Note that NMR imaging is accurate enough to resolve the prepuce: actual clinical imaging should be able to resolve this issue once and for all.

The degree and angle of direction and extent of bending depends on which position and the specific angle at the hips -- I do not know about you, but reverse cowgirl hurts me. All and all, the neutralness of the bend does not effect the accuracy of this image. if the couple in the NMRI could have one of them go into a more vertical angle (impossible in the imaging chamber), then the bowing would be less. As it is, the bowing can hardly be called "boomerang-shape." I see no reason not to restore the image.

Merge tag

I have added the mergeto tag. Sexual intercourse is already understood as a men inserting his penis into a woman's vagina. --Philo 12:23, 25 July 2006 (UTC)

Yes, but vaginal sex is not the only kind of sexual intercourse that can be performed, so a merge would be incorrect as it would imply that vaginal sex WAS the only type of sexual intercourse. Please give this some thought. —Preceding unsigned comment added by 71.76.144.236 (talk • contribs)

In the best interest of the accuracy of Wikipedia, please give some thought before posting a merge. Thank you, and may you have a wonderful day. Please be certain that a merge would be in Wikipedia's best interest before you consider merging an article into another.—Preceding unsigned comment added by 71.76.144.236 (talk • contribs)

Against - The topic of intercourse is broad, as is clear from the current article, and its existing inadequacies. Vaginal sex, is more specific, and can talk more about the aspect related to sexual pleasure and kinkier sex (vaginal penetration by things other than a penis, and also for reasons other than reproduction.) The "Sexual Intercourse" article is more clinical and Biological. Atom 00:22, 6 August 2006 (UTC)
