[This article may be very offensive to you, but you can learn about the relationship between the penile/vaginal temperature and orgasmic response, and the relationship among the urogenital blood circulation, urinary continence, androgen hormones and prostaglandin E-1. For a better sex, keep your penis/clitoris/vagina hot, but your brain cool; that is, pump your blood down to your sex organs, but not to your brain during lovemaking until you reach an orgasm as shown in http://www.actionlove.com/cases/case1217.htm!  Their sexual adventures in helping us cross-verify our long-term hypotheses should be highly appreciated! ]

Case Title:  After her husband failed to maintain his erection for her, she is interested in dog sex for sexual orgasm. Can she have a dog tie? Dr. Lin's saddest advice! Updated (3/17/2004): She had experienced powerful multiple orgasms with the high-temperature dog penis and semen (3 degrees F higher than the human's). The result of the Dog Sex experiments can lead to a new powerful therapeutic concept for urinary incontinence! Why?

Reader: 3/15/2004>

My husband has recently been through many physical problems. He is unable to achieve an erection for very long. I have a need to receive physical pleasure and don't want to have another man as that could create unwanted complications.
I have a male Rottweiller that has very large erections( he has a penis that is about eight inches long including his bulb. I constantly fantasize about my dog fucking me and giving me the pleasure that I want so desparately. My question is: should I let the bulb penetrate me? I was wondering if the bulb would harm me in any way? I get very horny when I think of the dog fucking me.
I am sure that my vagina can take the large penis and the bulb. I just wanted to know also how long would the dog a me be 'hooked up?' Oh, by the way, my husband is very much in favor of our dog fucking me, and he would assist in the coupling.
Thank you for your expertise opinion and timely reply.

Dr. Lin: 3/15/2004>The dog tie (hooked up) is due to spasms of the female dog's uterus when the glans penis penetrates into the cervix and uterus.
This won't occurs in the human's cervix/uterus since the women's cervix orifice is very tight and have an 30-45 degrees angle with the vaginal axis as shown in http://actionlove.com/image/attack.jpg 
The dog cervix orifice is very big and in line with the vagina/urethra-axis. This allows female dogs to deliver a lot of poppies without a midwife or an OBGYN. I have never heard female dogs having a labor difficulty.
Since the dog's vagina and urethra share the same existing canal, the big opening of the dog's cervix is to allow the dog's glans to pass through and then lock it up with continuously uterine spasms until the male dog fully exhausts his semen and sperm and his bulb shrinks back. In this way, the semen and sperm are directly injected into the uterus, rather than into the vagina, to make a lot of poppies. The dog tie is a result of the trapping (locking) of the glans penis inside the uterus/cervix when the uterus/cervix is spastically contract. It can be untied when the uterus and cervix are fully relaxed by sufficient prostaglandin E-1in the semen too.
In human beings, the female urethra and vagina are separated with a erectile spongy tissue while the G-spot is hidden inside, about 1-3 inches deep , as described in http://www.actionlove.com/love/g-spot.htm 
and the Epicenter is located at the ending of the urethral/vaginal spongy tissue, between the cervix and bladder.
Stimulating these points allows women to achieve orgasm, instead of uterine spasms for the dog tie. 
So, you won't be locked up by the dog penis since there is no much chance for it to pass your tiny cervical orifice, unless your cervical orifice is widely opened and in line with your vaginal axis due to uterine/cervical titling or rotating as shown in http://actionlove.com/image/u-relap.jpg

Dr. Lin,
Being fucked by the dog and his bulb entering me will not harm me in any way correct?
Will it still bring me to an orgasm? What are the "levels" of orgasm that you refer to? Can the entering of the bulb give me a greater orgasm?
Again, thank you for answering these questions for me,
Dr.Lin: 3/16/2004>
" Being fucked by the dog and his bulb entering me will not harm me in any way correct?"
It is supposed not to hurt you.
If you experience penetration or thrusting pain or cramp, it is due to a lack of the prostaglandin E-1 production in your vagina/cervix/uterus or due to a titled or prolapsed uterus. This is called vaginismus (penetration/intercourse pains)
as discussed in http://www.actionlove.com/extra/vaginismus.htm 

"Will it still bring me to an orgasm? What are the "levels" of orgasm that you refer to? Can the entering of the bulb give me a greater orgasm?"
It depends on
1. if your brain's dopamine and testosterone level can ignite orgasmic fire to burn dopamine into adrenalin for the contraction of the tissue and blood vessel
2. if your pituitary can release enough orgasm hormone oxytocin to initiate the uterine contraction.
3. if your uterine/cervical/vaginal tissues produce sufficient Prostaglandin E-1 to amplify the orgasmic contraction without pains or cramps.
4. if you get a rhythmic stimulation in your G-spot or Epicenter (likely a deep penetration to the Epicenter) and if you need a stimulation of your clitoris to open your sexual energy gate for orgasmic energy to run up to your heart/lungs and forebrain ( http://www.actionlove.com/image/trigger.jpg and http://www.actionlove.com/image/wavepath.jpg ) .

The dog body temperature is about 3 degrees F higher than the human body. Assuming his penile or semen's  temperature is 3 degrees higher than your vagina/cervix, it can excite the Epicenter nerves to sign your pituitary for a flooding of oxytocin into your bloodstream, and at the same time, promote the vaginal/cervical/uterine tissue to produce a lot of Prostaglandin E-1 for orgasm, with a little action (thrusting), as long as your brain's dopamine and testosterone levels are high.

Note: To elevate 3 degrees in the vagina, urethra and cervix during human lovemaking, it requires a high-speed and high-pressure stimulation to burn testosterone into DHT in the local tissue, as described in http://www.actionlove.com/love/method.htm  ; http://www.actionlove.com/love/fgpliers.htm  ; http://www.actionlove.com/love/resonant.htm.  I believe the temperature elevation in the G-spot and Epicenter auto-contractile and auto-rhythmic tissue and the sympathetic sensory and motoring nerves that link to the pituitary play an important role for vaginal orgasm.

Since I wrote you last Dr. Lin, I have been fucked by my Rottweiler twice. My husband assisted in the coupling and was very turned on by how the dog fucked me. The dog fucked me for about thirty minutes each time until he was absolutely exausted. The dogs seman ran out of me constantly while he was fucking me and for about three minutes after he withdrew his penis. I had multiple orgasms that were felt at the clitoris and deep in my epicenter. My husband measured the length of the dogs penis from the tip, in all I was able to take his entire ten inches. That is from the tip to two inches behind the bulb. I was soooo turned on and it felt terrific. The dog spent quite awhile licking my inner and outer lips and clitoris. The sensation was awesome and opened my vagina wide for the penetration. His penis not only penetrated me to the depth of 10 inches but my husband measured the circumference at four inches. It was such a turn on to see that huge penis before it entered me. It took a little while for me to take it all but I was so horny just seeing it going in me that it didn't take long at all! It was a great coupling and my multiple orgasms were beyond great. My husband was wonderful helping me and the dog hook up. He helped the dog connect with me while on my hands and knees. The second penetration was while I was on my back. I was elevated on a short table covered with a foam pad. This second penetration was the next day. As I said my husband was great in helping the dog to find my vaginal opening. My husband and I talked about the frequency of the dog fucking me. We decided that as long as I remain pain free we will have the dog fuck me two to three times a week. We have had the dog checked by our Vet, and he is free of any harmful bacteria. I wash the dogs penis before each penetration with a hygenic solution to insure its cleanliness. Thank you for your reply. I remain, MG 

PS I would have never submitted to being fucked by a dog, but since my husbands recent illnesses and his erectile problems he wanted me to have another man. I didn't want to do that as it could have created problems between my husband and me. I was turned on eventually by the thought of my dog fucking me. My husband, as I said before, was the one that suggested it. I now have the sexual outlet that I desired and no complications of another man.

Dr. Lin: 3/17/2004>
Generally, a high temperature penis and semen can trigger multiple orgasms.  The hot semen flow, like a lava flow,  can trigger multiple orgasms for women.
The first orgasm is located at Epicenter, deep inside the vagina between the bladder and cervix, under the stimulation of the hot glans and semen; the 2nd orgasm is around the G-spot due to the outflow of semen; the 3rd  one is near the vaginal orifice and urethral nervous endings when the hot semen reaches the nervous endings of the vagina/urethra and the penis still gently thrusts the vagina in and out.
The dog body temperature with 3 degrees higher than the human body has this advantage.
With a 10 inches long and a 4 inches wide bulb having a 101 degrees heat, the dog penis can let your volcano to explode with a gentle thrust.
As long as your husband agrees to let you enjoy the dog sexual orgasm therapy, there is nothing wrong.  In fact, it may give you a positively benefit for urinary and bladder control since the high temperature penis and semen can promote pelvic blood circulation and the prostaglandin E-1 production in your urethra, vagina, cervix, bladder and uterus. I believe, sooner or later, the medical society will "discover" this new treatment for female urinary and bowel incontinence with dog sex.  It is more powerful than other drug treatments or the so-called bio-feedback vaginal insertion device. The dog penis and semen are the optimal heating device (3 degrees higher than the human body temperature) and prostaglandin E-1 stimulator.
At least, it is better than a vibrator which can damage your pelvic nervous function as shown in http://www.actionlove.com/extra/vibrator.htm 

How did you learn sex?  ==> http://www.actionlove.com/love/animal.htm 

Note: Pregnant horse urine has been used for producing the Hormone Replacement Therapy drugs for menopause women due to its contents of a high level of animal-placenta estrogen and progesterone. In the Chinese Medicine, the dog penis and testicles have been documented as medicines for replenishment (enlargement ?) of the human penis due to its concentration of the androgen hormones testosterone and DHT.  How about the dog's semen?

Dr. Lin,
Which of your products can restore my penile erections. I would like to have sexual relations again. I really like watching my wife being pleasured by our dog but I would like to fuck her again. It turns me on to watch that huge dog penis fucking her but I want to copulate with her too.
My penis will only erect for a couple of minutes.
Thank you for help
Dr. Lin: 3/17/2004>
A low dose of ViaPal-hGH-P(3-010) and 5_HTP (2-001) can help you gradually restore and prolong your erection.

Because of my positive experience with my dog fucking me vaginally the last couple of days, I wanted to let him fuck my asshole. I got on my hands and knees
and my husband had to keep the penis from entering me too fast. Once the spincther muscle relaxed, I told my husband to let the dog stroke me at his normal speed. We allowed the penis to penetrate up to the bulb and slowly I was able to accept the bulb. The bulb penetrated beyond the spinchter,which took a little time to allow penetration of the last two inches of the huge penis( I was able to receive the entire 10 inches, the eight inches from the tip and bulb and the two inches behind the bulb. The spincter muscle opened wide enough to allow the bulb into me but closed down on the last two inches behind the bulb. As a result, the dogs penis became tied up inside of me for about thirty minutes and the penis continued to spasm inside of me. It was very satisfying feeling the ejaculating of the hot seman into my asshole. It felt so good that I had a couple of orgasms from it.
My husband was so turned on that he got underneath me and penetrated my vagina.
Boy did it feel full with both my asshole and vagina being fucked simultaneoulsy.
The dog was ejaculating into my asshole and my husband ejaculated in my vagina. During this phase I exploded in a third orgasm. Needless to say there was a lot of discharge flowing out of both my holes after they were through fucking me. My asshole was open for about a half hour afterwards. The open anus closed but has been in a puckered state ever since. I want the dog to fuck me in the asshole again after I have given it a few days to rest.
We lubricated my asshole with KY jelly and it enabled the large dog penis to penetrate easier.

Can anal sex harm me in any way, if I do it too much?
Can simutaneous penetration by the dog and my husband harm me in any way?
Is there any benifit to my asshole and rectum from penetration of my dogs penis, as you said there was for the dogs hot penis and seman( three degrees F warmer) fucking of my vagina, such as preventing urinary incontinance?
Again I thank you for your timly reply. I am glad that I have someone to report my sexual activities to that is knowledgeable and unbiased.
Dr. Lin: 3/19/2004>
Since the anal and rectal tissue are not equipped to accept the intrusive object and frictional abrasion. It is more delicate than the vaginal tissue and its nerve is not well protected as the vaginal nerve, due to the fact that vagina canal is for intercourse and baby delivery.   The urethral tissue and nerve is much more delicate than the anal and rectal tissue and nerve. That is why the urethra duct and nerve are protected by an erectile spongy tissue.
Anal Sex can cause the bowel incontinence as an excessive stimulation of the urethral nerve can result in urinary incontinence.
Please read -
& again, Anal Sex causes her bowel control incontinence for no sexual orgasm

Double penetration sex usually put a lot of stress and strain on the urethral and anal rectal tissue and nerve.
The main problems are the anus and rectum tissues and nerves may eventually react to or  be irritated by the directly ejaculating semen without passing through the digestive tract although absorption of a hot semen with a load of androgen (DHEA and androstendione)  hormones and prostaglandins  via the vaginal tissue generally helps urinary continence.

Dr. Lin,
Thank you so much for your reply, and expertise in sexual activities.
You have been a great deal of assistance to me.
I will discontinue the anal penetration by my dogs large penis.
I respect your insights on this matter.
Again, thank you for your candid answers.
One question before I go: can the penetration of my vagina by two penises harm me in any way. My husband would like a friend of his to fuck me, and I have consented. I had said that I wouldn't want a sexual encounter with another male , as it could cause unwanted complications, but this is not just someone off the street, as it were. At my husbands request I am going to give it a try. They have talked about it and his friend was hesitant at first, not wanting any complications. He is not married and isn't seeing anyone at the moment. We have all talked about it and as a result the three of us are very horny and looking forward to it. My husbands reason for us doing this is it will help him have an erection and fuck me. He has had a raging hard on every time we have talked about doing it.
After I said yes to fucking his friend (something I really want to experience) my husband and I have talked about a double penis penetration. . I am now looking forward to having both of them fucking me at the same time.. I will be fucked by one at a time, until I am really hot, and then I will accept them into my pussy at the same. .I don't think two penises fucking me at the same time would be harmful to me, but I won't do it until I hear from you.
Thank you for your valuable insights in sexual intercourse.
Dr.Lin: 3/19/2004>
The problem is: When the 2 penis penetrates into your vagina, the 2 penis can not move; even if one moves, it will be against the other. Besides, it will over-expand your vagina. I don't think you can achieve orgasm with 2 penis inside your vagina because they can not pinpoint your itchy points, but stuff up your vagina.
The double penetration play with one into your anus/rectum and other into your vagina is different since the one inside your anus/rectum will deflect the other inside your vagina to stimulate your G-spot, Epicenter and urethral nerves. Thrusting of the penis inside your vagina may give you a lot of stimulation for orgasm. Inserting a soft dummy penis (didlo) into your anus/rectum during intercourse can deflect the thrusting penis (erecting!) inside your vagina to stimulate your G-spot, Epicenter and urethral nerves for orgasm. In this way, you don't need a 3rd party in your lovemaking.
The psychological factors: If your husband can not erect his penis or hold his erection, he will become a loser and assistant in this sexual play. If his friend solely gives you pleasure, you may emotionally attach to his friend and your marriage will become very complicated. "Making love" means sex can develop a relationship. This is a very dangerous game for your marriage. I encourage you to fix the problem within your marriage. Let me introduce both of you some sexual tricks and orgasmic excitation principles in
so that you don't have to rely on the third party.
