Disclaimer: This post isn’t meant in a bragging “look how big one of my sexual partners was” sense, but to clear up something that’s been bugging me.
A couple of weeks ago, I was having anal sex with this guy who had a fairly large penis. As I was receiving said penis in the poop chute, I noticed some discomfort at the point of full penetration, like he was hitting something inside (not the prostate, something deeper). My only guess was that he was hitting the bend as it goes up into the descending colon, but I’m not sure how the angles of all that work out. Wikipedia says that the rectum is only 12 cm long, which seems to me a little short, because most of the men I’ve had sex with have been over 12 cm long, and I have a 9" dildo at home that I know is more than that.
In joking about it with a friend, I called it my man-cervix, because I hear the lady folks sometimes have a similar thing going on, but when I discussed it, I realized that I really had no idea what it could have possibly been. This happened in various positions, although missionary, which I’ve always found allowed deeper penetration for me anyway, had the most pronounced effect.
But surely the stool doesn’t have pain receptors. Or did you mean that the mechanism involved the stool being pushed up the tube and causing pressure that way?
Maybe the coccyx bone if deeper than the prostate? Though then the next question would be to try to figure out WHERE he was hitting it from- ie: was it directly in front, pressure above or below, etc?
Otherwise, :shrug: I got nothing. If it’s not a common occurrence or at a fixed distance, then yeah, Stool’s the best guess?
I know nothing about anything, certainly not anal sex, but one thing I’ve long been curious about (I’m going to reveal myself as an idiot now) is how it interplays with the fact that stool may be lying in wait at some point in there. I mean, I’m curious; at a suitably generic moment, how “far down” can one expect stool to be waiting in their colon, so to speak? That is to say, supposing one is not in that particular stage where they need to have a bowel movement right now, how far up the rectum/colon would one have to go to find the next bowel movement on its way? I suppose it would have to vary continuously (i.e., sometimes far up and sometimes not so far up, depending on how soon your next bowel movement would be). But that’d seem to make anal sex very tricky (on the assumption that it generally does not involve interaction with large amounts of waiting stool). But, like I said, I don’t really know anything about (and am clearly not personally acquainted with) anal sex, so surely the actual mechanics here are less tricky than I would think; perhaps by the time stool is within such area as that it might interact with penetration, one is generally just about to vacate it with a bowel movement already. Boy, I must really sound like an idiot here, but it has been something I’ve mulled over with silent curiosity sometimes.
I have nothing that might help the OP, but Indistinguishable, you’re about to get a crash course. Welcome to Anal 101!!
IANAExpert (yet) but it is true that stool can vary widely as ar as where it is when anal sex occurs. Many factors come into play here, such as how long ago your last meal was, what types of things you ate, and how regular your BMs are on a day-to-day basis. For example, if cheese is a known contributor to plugging you up, and you eat lots of cheesy foods - that haven’t had time to clear your digestive tract - there’s a high likelyhood of encountering a solid mass upon penetration. (This solid mass can be painful to the giver and/or receiver of the anal sex, so exercise caution and good common sense!) A good rule of thumb for those considering this type of endeavor is to A- eat something light that won’t produce such a large, solid mass, and B- partake of an enema to help flush out any unpleasant surprises that may be waiting in the wings, so to speak.

Discussed anal sex with a gay friend this weekend. He said there are two sphincters near the opening and a third about nine inches in. Most people never have to worry about the third sphincter. Maybe your friend hit it.
I just stumbled through that section of Gray’s Anatomy (the book, not the TV show.) It describes the rectum as 8 inches long. An inch or two inside the anus, it turns toward the spine. Then it traces a rising curve along the back of the abdominal cavity. If you encounter a partner who just jams it in any which way instead of following where it goes, your rectum will stretch and flex to accommodate him up to a point. At some point, it’s going to hurt.
Think of a question mark. ? Now, picture bending open the curved part until it’s a gentle curve, ending straight up. That’s your rectum, more or less.
I saw a bit of behind the scenes thingy of a porn movie, wherein the actress was going to receive the rather focused attentions of an actor on that particular opening. She would enema before hand, to be as clean as possible.
There would be a LOT of lube. Lots of it.
And she still had a depend she would wear on her drive home, as lube and such would leak out.
Yeah, that’s what I was trying to say, but I figured a clinical approach was best, since this is GQ and all. Apologies if my explanation was a poor one.
(That follows the two click rule BTW, but don’t visit there while at work and I’m disabling the automatic linkage.)
Tristan has written a couple of books - admittedly for women, but how much different can it be? - on the subject and has a section on her site called “Anal Advisor” with a sub-category called “Discomfort and Pain” with two questions in it titled “Road Block at 4 Inches” and “Sphincter Muscles”. I’m not linking directly to them for obvious reasons but I trust you can find them yourself. Poke around.
I’m shocked. The ad at the bottom of the page for me is “Microfinance Empowers - Join us in enabling the poorest of the poor to improve their own lives.” Try as I might, I just can’t connect that to the subject at hand. A more open invitation to blue advertising there never was. I never thought I’d see it, but I think chaoticbear has broken the intarwebz.
