This seems pretty cool although what's this blog?
Can you post a link to that?
Also If you're gonna do diferent sizes I'd recommend the average size. Also include the diamter or girth of the penis as well.
I'm guessing eventually you're aiming toward some sorta 3D model where you can adjust the sizes of everything and stuff to see how it would play out or maybe illustrate why someones having problems with their gf as you can see whats happening inside?

Is the rectum longer than the vagina?

Length is not as much of an issue as long as I dilate using a long dildo before we have sex.

There's a different problem we have with anal sex. Preparing for anal sex is the kind of time consuming activity that doesn't work out very well if you have a baby in the house. Doing things that take a lot of preparation or foreplay isn't ideal. Inevitably, he'll wake up before you've gotten to the "having sex" part. :frown1:

I've been saying this for a few years that logically a anyone with a penis 3-4 inches or bigger could hit a woman's cervix.

I had a really good planned parenthood teacher in high school. She used to talk about all kinds of random sex topics. This is one of the many things she used to go off about that I always remembered.

Great job the photos are awesome. Mind if I follow you on tumblr?

That's what I meant, probably anal sex is better for a long dick.

I dunno. We're all built a little differently. I can't confidently say that generalizing from my experience would be correct for most women. That's a lesson I've learned well from getting to know the other women here and talking with them about their anatomies and tastes and issues. Until other women share their experiences, I'd remain open-minded.

Great stuff, RD. Thank you for the very illustrative work. What software were you using?

Thanks! I'm using AutoCAD 2010 and just doing a screencap and saving it as a jpg file. I'd use a Paint Program, but the dimensions are key for me and much easier using AutoCAD. I've finally successfully imported it into Adobe Flash. Animating it is my last hurdle.

I like the engineer comment, you make this all so scientific!

Thanks, because indeed I am an engineer. On paper anyway. I never got my P.E. license because I burnt out right before I graduated back in '86.

I've been wanting (and have had the background) to do this for years. Frustration trying to explain "the motion in the ocean" is what finally prompted me to do this.

This seems pretty cool although what's this blog?

Technically, tumblr is supposed to be a blog. I'm not too savvy with the ins and outs of the formatting and really have no interest in airing my views in a blog. I use it more as a repository for my images so I can post it and not have anything traced back to me personally IRL.

This place and my posts here is my "blog". A lot of traffic with like-minded people with a lot of fresh perspectives.

Can you post a link to that?

Sure:

http://www.tumblr.com/blog/inyourcunt

Also If you're gonna do diferent sizes I'd recommend the average size. Also include the diamter or girth of the penis as well.

Bingo! This is a few months down the road, but it is something I definitely want to lead up to.

I'm guessing eventually you're aiming toward some sorta 3D model where you can adjust the sizes of everything and stuff to see how it would play out or maybe illustrate why someones having problems with their gf as you can see whats happening inside?

You guessed correctly. Right now this is all a pastime, but my wife and I were discussing what I could possibly do in, say 5 years, to leverage this into something monetary. That idea was raised in our discussions over the weekend.

Not sure I want to think about it in that context... yet. I'm enjoying the little exposure I've had in the last couple of days.

amazing analysis

Thanks!

Hmm, I like where your mind goes sometimes! I wanted to color code the objects so I can differentiate the bits and the physics. Blue = Boy, Pink = girl.

What's a cu-de-sac? I've never heard that in the sexual sense...

Ahh.. a whole new world may be opening up for you. Read this:

It seems so logical, but it really isn't to people who don't give a rat's ass what they're doing in there.

The problem with growing up Catholic in an all-boys school is that we didn't have any sex education to speak of. Nothing aside from, "It's a sin".

Great job the photos are awesome. Mind if I follow you on tumblr?

Thank you! No, I don't mind. Although like I said earlier, there really is no structure in my tumblr blog, just a place to upload my images and a watermark to draw traffic (and more people to discuss).

I like your drawings.

I think it is important to note that the sagittal section diagram of female anatomy on which your schematics are based does not apply to all women. It shows a typical anteverted uterus lying over the urinary bladder. This anatomical arrangement might describe the majority of women, but quite a few have a vertical or a retroflexed uterus:
Retroverted uterus | Better Health Channel

In those women with a retroflexed uterus, the cervix may not project into the anterior aspect of the vaginal canal. It may project more end on into the vagina and be much more likely to make direct contact with the penis during sex.

Also, the penis does not necessarily enter the posterior fornix, as you show, during deep penetration. MRI imaging has confirmed that it may (at least in some cases) be directed towards the anterior fornix during face-to-face intercourse, and a normally anteverted uterus might actually retroflex rather than draw forward during intercourse.

I suspect that exactly where the tip of the penis winds up is going to vary with the couple's particular anatomy, as well as the position used.

I can tell you that I had a couple of partners with whom there was no avoiding their cervix in some positions. It simply wasn't possible to "slide past it" as shown. With these women, certain positions were absolutely off-limits.

As a former owner of a retroverted uterus, everything he said is 100% right on. You HAVE to include that there are a great number of women out there who do not have "textbook" anatomy. Hitting areas that aren't where they are supposed to be during sex is like getting a paper cut. You shriek and shutter at the thought of how it just felt and how much you dread EVER having to go through that pain again.

No, he can't. Linking to personal blogs is against the ToS and results in sanctions (although you CAN put a link in your sig).

The images posted so far are okay IMO, because there is no blog as yet, just a few images.

RD, I'll do a proper response to this thread later today when I have more time!

Hmm I had no idea they didn't teach sex education, even a little bit. I took extra classes on it in High School because they offered them.

I still followed the tumblr for the images, it's really neat to share.
