Anal Eroticism: Self-administration of an Epoxy Resin Adhesive into the Rectum

A case of a man who administered a liquid used as masonry adhesive into his rectum for anal sexual gratification has been reported.(1)

This case is similar to the insertion of a concrete mix by a homosexual into the rectum of his partner during anal play.  Here is the case description:

A 27-year-old unemployed young man presented with lower abdominal discomfort following injection of a liquid adhesive per rectum 5 hours previously. He injected the viscous liquids into his rectum via a dual-chambered glue gun, resulting in an instantaneous exothermic reaction that caused the mixture to solidify and become fixed internally. He had no previous history of bowel disorder or psychiatric disturbance. The patient admitted he had done this for anal erotic enjoyment. The apparatus was examined carefully, but apart from a company name and a product code number, there was no clue as to what chemical had been present in the dual-chambered gun. A general Internet search using just the company name and the product code number was performed. This led us to an exact photograph of the glue gun and a precise description of the adhesive. The product contained 330 ml of epoxyacrylate resin. The resin was supplied as a dual cartridge, which, in addition contained dibenzoyl peroxide and styrene. Final mixing of the chemicals occurs in the nozzle upon squeezing the applicator gun trigger, discharging both chambers simultaneously. It is meant for use in the building and construction trade as a masonry adhesive.

“On rectal examination, a rock-solid foreign body was both visible and palpable just inside the anal sphincter.  A plain abdominal x-ray showed a radiopaque foreign object following the exact contour of the rectum stretching from the anal canal to the rectosigmoid junction,” a distance of 16 cm.  See the X-ray below.

The surgeons tried to remove the hardened resin by using an oily enema and their fingers, but it had molded itself so well to the contours of the rectum that there was no option other than to go for a laparotomy (a surgical incision into the abdominal cavity).  “With gentle manipulation of the rectosigmoid junction, it was possible to deliver the rock-hard material through the anus along with copious mucus discharge and a small amount of blood.”  Fortunately, the rectal wall was intact, though inflamed and swollen.  “Bearing in mind the possibility of full thickness “burn” of the rectal wall and potential risk of later perforation, a loop sigmoid colostomy was raised in the left iliac fossa and the abdomen was closed.”

A loop sigmoid colostomy is a colostomy at the S-shaped part of the colon, and involves bringing a loop of bowel through an incision in the abdominal wall, utilizing a plastic rod to hold the loop in place, and then making an incision into the bowel to allow the passage of stool through the loop colostomy.  The patient had to live like this for a few weeks till tests revealed that his rectum was fine, allowing the surgeons to put back the extracted portion of the bowel and close the abdominal opening.

The photo of the extracted object is shown below.

The surgeons offered psychiatric counseling to the patient, but as one would guess, the patient declined.

Are you sure that was self administrated for anal sexual gratification?. I think the contrary. Most likely, this is a case of gay-gay violence which is far more frequent and brutal than the so called homophobic violence.

Rocco: The case report clearly specifies that the resin was self-administered for the purposes of anal erotic enjoyment.

Wow Erik Holland, you sure do seem fascinated by gay guy’s assholes. Any special reason why you have this particular interest?

Posted by raot on November 18, 2006 at 02:22 AM | #

Raot: Entries like this go toward describing the nature of gay sexuality, especially the more unflattering aspects of it.  This in turn is relevant to understanding homosexuality.  Hence the entry.  I don’t have any fascination for the anorectal region of homosexual men.

Posted by Erik on November 18, 2006 at 11:51 PM | #

If one claims to have no interest in gay men’s anuses, it makes no sense to also claim to have an interest in gay sexuality. The anus and what is done to and with it is part of gay men’s sexuality, thus an interest in gay men’s sexuality includes interest in their anuses.

Sorry to draw the unflattering aspects of your own sexual obsessions to your attention. Posts like mine go toward describing the nature of sexuality researchers such as you.

Posted by Raot on November 19, 2006 at 12:50 AM | #

Raot: Gay sexuality is not just limited to what gays do with their anorectal regions; there are plenty of other issues involved.  Gay sexuality needs to be addressed in order to understand the nature of homosexuality, and documenting it does not imply that the author somehow has a special interest in it.  Understanding the nature of homosexuality also requires that one address issues other than sexual behaviors.  For instance, this site extensively addresses the mental health aspects of homosexuality, yet I have not come across anyone accusing me of being obsessed with how mentally healthy homosexuals are.

I don’t think anyone’s fascinated by homosexual men’s anuses other than homosexual men.  But, if there are people doing such stupid and bizarre things as pouring concrete in their anuses ‘for pleasure’ - well, I need a good laugh.  And yes, its very funny...almost as funny as the light-bulb...when most people have an idea, one goes off just above the head.  Maybe when you’re a homosexual and you have an idea, one goes up your anus.

Sounds very healthy and positive though...have to admit...concrete in the ass.

More proof that a man stupid enough to want another man to do him in his anus will be stupid enough to try anything. As for Raot’s laughable assertion that any man who comments about the concrete punk’s colon being “fascinated: by fag’s assholes, what a joke Roat is, trying to accuse normal men of being fags just because the normal man comments about a fag’s self-inflicted concrete constipation. Nice try, Roat, but it doesn’t work. Now go get AIDS..

David: Please avoid the f*g word.  I would not wish HIV infection/AIDS upon homosexuals or anyone else.  I hope that homosexuals prompted to indulge in dangerous behaviors—such as in the case reported—seek a mental health counselor for their own good.

Posted by Erik on March 04, 2007 at 06:03 AM | #

What does this have to do with homosexuality?  Seems more like Auto-eroticism to me.

If anything else it was really stupid to do.

Posted by Mike on March 05, 2007 at 09:46 PM | #

Mike: What kind of men indulge in the type of sexual behavior documented, namely inserting objects into their rectum for sexual pleasure?

Posted by Erik on March 07, 2007 at 04:38 AM | #

What I find amazing about this article is that you are only targeting this as something a gay man would do.  There are 1000’s of documented medical instances where heterosexual people have come into the emergency room due to performing some “perverted” sexual act upon themselves that would be considered abnormal by the rest of society.

Women with a vast array of items stuck in their vaginal areas, men who have gotten their penis stuck in numerous different ways in objects they clearly shouldnt have been sticking their penises in, etc…

Posted by Robert Williamson on March 20, 2007 at 06:50 PM | #

Erik:  That is more of a paraphilia than a sexuality.

A paraphilia like necrophilia or pedophilia or foot fetishism is sexual arousal from an object, human, non-human, or otherwise.  It’s arousal from the superficial. 

A sexuality involves romantic, sexual, and emotional attraction, it’s far deeper than a paraphilia.

Posted by Mike on March 25, 2007 at 03:57 PM | #

Robert: You need to quit coming up with a caricature of the arguments within this site.  Of course, there are heterosexual individuals, too, who indulge in bizarre sexual practices, but what is pertinent is a comparison of frequency.  Some homosexual/bisexual men and also some heterosexual women insert objects into their rectum for sexual pleasure, but even though heterosexual women far exceed the number of homosexual/bisexual men, the typical patient with a stuck colorectal foreign body is a male homosexual.  Homosexual men are also overrepresented among men sticking their phallus where they would not be medically advised to (example).

Mike: The behavior described is neither a paraphilia nor a “sexuality.” It is a bizarre sex act, but the theme involved is one of anorectal eroticism, which is a major characteristic of homosexual and bisexual men and also some women.

Posted by Erik on May 09, 2007 at 07:17 PM | #

Your examples did not indicate the men were primarily homosexual.  Other than the ones who indicated they were homosexual, how can you make that reference of the ones that did not.  There are many heterosexual men who find pleasure in anal masturbation. I would like to know the percentage, in relation to population, of straight men, bisexual men, gay men, straight women, bisexual women, lesbians who present these cases to the ER.  That would be an incredibly hard research task.  Especially with all the HIPAA regulations.

Also, I have never heard of an acutal case from any colleagues where a male has presented himself to the ER with his penis in a bottle.  I have heard about that but I was probably 10 and it was about a boy at school that everyone picked on.  On that same note, to this day none of us knew if he was gay or not.  But, in my adult life, I have never heard of a “penis in the bottle” incident.

Again, anal eroticism is also present in straight men.  It is becoming less and less a strictly homosexual act. 

Your being a little confusing.  How can you state that the article above is not about sexuality but about bizarre sex acts when you are stating its homsexual in nature, which is indeed making the assumption that your bizarre sex acts are geared towards a sexuality.

You are right, most of the incidents that would be described above would not be considered paraphilia.  Paraphilia is being sexually aroused by an act or object.  This is not a singular act or object but one that would always cause an arrousal.  For example, a particular type of underwear, exposing oneself in public, etc… which would then result in sexual gratification and not always involving masturbation.

Posted by Robert Williamson on May 10, 2007 at 04:35 AM | #

Robert: Many heterosexual men find pleasure in anal masturbation?  Are you insane?  What is the point of being a heterosexual man if there is a desire for being penetrated by a phallic-shaped object?  Among men, a desire for being rectally penetrated occurs among homosexual and bisexual men, not heterosexual men.  The minority of heterosexual men interested in anal eroticism are interested in the anorectal region of women, not their own.

I cited a literature review reporting that the typical patient with a stuck colorectal foreign body is a male homosexual.  It is true that in a number of cases it is not investigated whether the man is exclusively homosexual or bisexual, but it is clear that these men have a homosexual component to their attractions. 

Inserting one’s phallus into a bottle is uncommon and hence few know about it.  I found out about this behavior only a couple of years ago.  In my reply to Mike, I used “sexuality” to refer to Mike’s usage of the word sexuality, by which he meant “romantic, sexual, and emotional attraction.” Lastly, a paraphilia is not defined like you have described it.

Posted by Erik on May 11, 2007 at 06:54 AM | #

ERIK you are incorrect.  Paraphilia IS defined:

As defined by
par·a·phil·i·a /?pær??f?li?/ Pronunciation Key - Show Spelled Pronunciation[par-uh-fil-ee-uh] Pronunciation Key - Show IPA Pronunciation
–noun Psychiatry. a type of mental disorder characterized by a preference for or obsession with unusual sexual practices, as pedophilia, sadomasochism, or exhibitionism. 

As defined by American Heritage Dictionary:
par·a·phil·i·a (p?r’?-f?l’?-?, -f?l’y?) Pronunciation Key
n.  Any of a group of psychosexual disorders characterized by sexual fantasies, feelings, or activities involving a nonhuman object, a nonconsenting partner such as a child, or pain or humiliation of oneself or one’s partner. Also called sexual deviation.

As defined by Websters:
Main Entry: para·phil·ia
Pronunciation: \?pa-r?-?fi-l?-?\
Function: noun
Etymology: New Latin
Date: 1925
: a pattern of recurring sexually arousing mental imagery or behavior that involves unusual and especially socially unacceptable sexual practices (as sadism or pedophilia)
— para·phil·iac \-?fi-l?-?ak\ or para·phil·ic \-?fi-lik\ adjective or noun

Here is a forensics definition of paraphilia.  I thought you might want to read it to you would have a better understanding of exactly what paraphilia is.

If you have a DSM-IV TR, it should be easy to reference what paraphia is.  That diagnosis is listed under the Sexual Disorder section.

And another arrticle:

As for your statement that NO heterosexual male enjoys anal eroticism of his own body (not that he likes giving it to a female), I thought you might want to reference this article.

If you will take note, there are several references in this artocle about heterosexual men and anal eroticism.  You can clearly see this information because the article refers to the males partner as FEMALE.

You are also being slightly victorian on your thoughts about sex.  Anal eroticism isn’t necessarily being penetrated by a penis.  It could involve rubbing, insertion of fingers or other obejcts, etc… The attitudes about sex and what it means has been expanding rapidly during this and the last century.  Sex isn’t always looked at as a means for reproduction (I’m talking about the heterosexual community and not the homosexual community).  Many sexual acts today among heterosexuals is merely for pleasure.  After all, every time you go to a bar to pick up a girl (as most college aged guys do), it’s not for the means of conception but for pleasure.  Anal eroticism isn’t a homosexual only act.

Robert: Interesting that Erik has chosen not to respond to your last post. Anal erotisism is indeed common among people of all sexual persuasions. The fact that we have the prostate positioned where it is and that men can reach orgasm through having it stimulated via the anus is testament to the fact that the anus has a deeply erotic component and therefore a part to play in human sexuality and erotic pleasure. The only thing that stops individuals like erik exploring their own anuses is their own self disgust. This website exists because it is an out-picturing , a projection if you like , of the creators own fears about his/her own sexuality. So...remember you can enjoy your anus and be a fully fledged paid up heterosexual without guilt or fear that you are gay and if you are Gay then so what?

Posted by david marsh on August 19, 2007 at 06:21 PM | #

Erik, I can only assume that you have some deep seating homosexual urges that caused you to create this site.  The prostate is reached via the anus.  It feels good for both straight and gay men.  I happen to be a straight man that enjoys a female giving attention to that part of my body.

Crawl out of your midwest, inbred, close minded hole, fool.

Posted by Jason on October 20, 2007 at 07:14 AM | #

I ditto Jason.

This all raises some interesting questions such as : should sex only be used to procreate?

Posted by drew on November 05, 2007 at 08:55 PM | #

I think anyone maintaining this site has an abnormal fear of gay people and is deep down gay himself, but just can’t deal with it.  The latent gay is always the gay that attacks other gay people as they feel they are about to be “exposed” to the world for their love of homosexual activities.  They cruise airport restrooms (Senator Craig anyone!!), rest areas along the highway, department store men’s rooms, and gyms and the like.  They have anonymous sex and are filled with intense shame and self hate.  To distract others from thinking they might be gay, they often boast of their “heterosexual conquests” which don’t really exist, they try to over compensate by making up ludicrous websites such as this, and they attack gay people much the way the Catholic Church does (they need to cover up the fact that 80-90 percent of all priests and nuns are homosexual). 

So there you have it on a plate so to speak.  That’s life, Celebrate it, Celebrate your own self and your own life.  Don’t let hate ruin your life such as the Monster that perpetuates this site.  He does a disservice to himself on a daily basis and must be in horrible mental pain in order to keep this going, he obviously is also a loner, with no friends and needs attention, doesn’t know how to have any sort of successful relationship with other human beings and is isolated from humanity.  I PITY YOU MY FRIEND.  WHAT A HORRIBLE BURDEN YOU MUST FEEL INSIDE, ALL THAT EMPTINESS, THAT PAIN, IT HAS SERVED YOU NOT SO WELL HAS IT?  I feel sad for you, I don’t hate you, I just feel sad that people like you breathe the same air as the rest of us and are allowed to live on this planet.  You, my friend, are a pathetic self hating loser.

I dont know if I have ever heard of something this bizarre in the sexual world. maybe i have been caged by my moral standards to even think up something of this nature.  I also feel that if you are a homosexual you are a bit psychologically unstable. I think that this man should have taken the therapy. To all homosexual,gays and lesbians: IT IS UNNATURAL AND IT GOES AGAINST GOD’S LAWS AND MANS LAWS TO ENGAGE IN THESE EVIL ACTS,EVIL IS A CHOICE THAT YOU HAVE NO BUISNESS MAKING.

Posted by chris on April 01, 2009 at 07:16 AM | #


If you don’t have anything intelligent to say, please don’t say anything at all.  To make a statement centered solely in religion is merely a statement of your opinion and nothing more.  And to clarify your own religious beliefs, you said “EVIL IS A CHOICE THAT YOU HAVE NO BUISNESS MAKING;” from what I have read of the bible man was put on this earth and given a free will to think and beleive what he wants.  So if I choose Evil, as you put it, that is my choice and a choice I have every right to make.  However, it’s not a choice.  I was born this way and am very happy and content being homosexual.  I could no sooner be “straight” than a bird could become a monkey.

"Many heterosexual men find pleasure in anal masturbation?  Are you insane?  What is the point of being a heterosexual man if there is a desire for being penetrated by a phallic-shaped object? “

This is probably one of the most shining cases of Erik’s lack of objectivity. He genuinely thinks barely any would do this?

OMG. Dont have any words

Posted by barbie games on November 08, 2010 at 09:00 PM | #

What I always wonder is why do gays feels it’s necessary to put things in their ass? There’s nothing about a gay man’s anus that is any different than a straight man’s anus. We both have the same exact plumbing and nerves. So why do gays think it’s so pleasurable to put objects or penises in their asses while straight men recoil at the thought?

Seriously, if I was gay, I’d realize that the anus wasn’t made for penetration and that nature designed it for a reason: as an EXIT ONLY tunnel. So if gays absolutely have to get down with a guy, why don’t they just give each other head or something? That doesn’t cause any damage I’m aware of. But decade after decade of ass-pounding is going to leave these guys with a prolapsed rectum. Either that or they’ll be wearing Depends by age 50.
