Dog sperm as a way to prevent unwanted pregnancy in women.

ZooAnim

Tourist
There are five of us, two dogs, two women and me a guy. We do it like this: when one of my women starts having a "fertile window" in her menstrual cycle, she's only fucked by two dogs all day. I don't touch her, I don't want my sperm to accidentally impregnate her. (both of my women are not on birth control pills). The dogs take turns fucking her four or six times during this time and flooding her pussy with cum.
On the first day of the "fertility window" of the menstrual cycle, the dog's sperm enters the egg and the dog's sperm briefly inseminates my beloved wife and the wife is sort of "pregnant" with dogs.
However, the chromosomes will not combine and the egg dies and the body removes the egg.
My lovely wife has been off birth control pills for a year.
Because she fucks with two dogs all day on the first day of her "fertility window" of her menstrual cycle, she doesn't get pregnant, and that's great. She after fucking with dogs the next day she's doing with me and four or more guys + she's having an orgy and she hasn't gotten pregnant yet.
It's our patent to keep her clean of chemical birth control pills and not accidentally get pregnant by strangers.
My wife and our mutual friend likes to fuck other men.
And I like it too when she fucks other guys in front of me. The dog's sperm is great because thanks to it my beloved wife and our mutual friend does not get pregnant. The five of us often have an orgy together. Then our mutual friend Viki who lives with us and my wife are fucked by two dogs and me.

Has anyone tried something similar?

Dog sperm cannot enter a human egg. Human egg cells have species-specific barriers (as do most egg cells) that only allow human sperm to enter.
Dog sperm is similar to human sperm. So if a human sperm enters the uterus during the "fertility window" of a woman's menstrual cycle, dog sperm will also enter the uterus. A dog's sperm will try to enter a woman's egg but the egg will reject it defending itself and die on its own. This will render the woman infertile in this menstrual cycle. The situation repeats every month.

I see. Would you care to link some evidence supporting this claim?

My wife can be proof of the effectiveness of this. She's been doing this for a year and hasn't gotten pregnant yet. Our mutual friend. She has been living with us for half a year and uses this method. Both ladies fuck dogs regularly. We also do orgies with lots of guys who fuck my ladies without condoms and flood them with cum. We also did fertility tests on both ladies. Both ladies are fertile and would have no problem getting pregnant.
 
to my kinda limited breeding knowledge, a canine sperm doesn't go straight for eggs like human ones do. girl in heat ovulates in waves during heat so the sperm is made to last few days, waiting for that. it's also what allows one litter to have multiple fathers even when different matings happened on different day within the heat period.

i also think the "dog sperm/human egg" pairing simply never happens due to species-specific barrier the eggs have.
 
But if a woman has a "fertile window" and the dog floods her with sperm, the dog's sperm will still get into the woman's egg. The egg will not be fertilized but will die and the woman will cease to be fertile in that menstrual cycle. Then she can fuck hard and let herself be flooded with cum without the fear of being impregnated.
 
In case anyone thinks to take this seriously (and I know most people should know better) the idea that sex with dogs can act as a contraceptive is 100% false. There is no legitimate evidence anywhere to support this idea.
There may be no scientific evidence that dog semen prevents a woman from getting pregnant. No one has officially investigated it. However, my wife has been doing this for a year and has not gotten pregnant. She doesn't take birth control pills at all. She fucks hard at orgies.
 
Yes, my wife is 40+. But our mutual friend is 22 and she's also been using it for four months and hasn't gotten pregnant. Both of my ladies fuck hard at orgies with other guys.
In my country we normally wait 12 months before beginning to help her getting pregnant. So 4 month surely doesn’t ‘prove’ anything. It is a fact that a woman past 40 years has a much lover fertility. And the mans fertility decreases too by age.
Whether the dog spermatozoa can enter her egg I don’t know.
Well, the idea of letting her be fucked many times by the dogs can probably reduce the possibility of pregnancy, simply because the dog ejaculates a much larger number of sperms than a man does. They all enters her womb, but the literally diluted human sperm enter a womb which is already flooded with dog sperm.

there isnt any research about it ---- BUT if you think about it pregnancy is about strongest seed reaching the fertile eggand dog sperm can enter a human egg and destroy it... so if you have a dog cuming alot inside a pussy and then you get a man who lets say ejaculates outside the vagina after he pounds the pussy then possibly the dog sperm help prevent pregnancy from possible seed leak from the man that sometimes happens (which is like a drop or 2)
but even full cum amount if the dog sperm catched the fertile eggs then yes it sounds like it is acting like birth control if it decreases the number of possible eggs aviable
 
No, it can't.

Stop dreaming.
explain why

because I know after the period where bad eggs are thrown with the blood and new eggs are in the system you get pregnant by the strongest seed who enters first

we already know as a fact that dog sperm inseminate the egg but then it collapses
 
Yeah this whole concept is wishful thinking. I won't say that dog semen has 0 impact on fertility but I imagine the worst thing for fertility is that it throws off the ph of the environment.

I have a pair of friends who are into zoo and would come over and we'd do all kinds of naughty fun. She was on no BC and still got impregnated.

but thats false daignoses because getting one result does not mean all the time
birthcontrol themselves are not 100% prevent pregnancies and also no one says that ejaculating to a girl who has dog semen in her would prevent 100%

In order to penetrate an egg, sperm need to bind to a specific receptor site on the surface of the egg. The receptor site of a human egg is not compatible with dog sperm. As such dog sperm is completely unable to penetrate a human egg, and therefore cannot fuse with it or kill it. Please read the thread next time, we went over this already.

Playing very fast and loose with the words "know" and "fact".

There's actually a biologist on this forum who posted an incredibly well researched and sourced and cited breakdown of why this doesn't happen. I can't be asked to find the post but it had much better sources than "dude, trust me".

Stop presenting your fantasies as facts before someone ends up pregnant accidentally.

I read the thread and telling someone that he is just wrong is not a scientific answer therefor I asked a very specific thing

was there an experminate made with dog sperm to see if it does not trigger the receptor because if it was done with diferent animal sperm thats not the same obviously

and even if it doesnt trigger the egg and makes it die dont you think that possible amount of dog sperm inside a woman vagina can cause the human sperm to work less efficiant

I was pretty sure I read that the sperm causes the egg to collapse and if you want to be honest all you did here in response to 2 people was telling them that they were just fantisizing so the attitude like you brought hardcore science into the discussion is not helpful because you didnt

Yeah, people have this idea the sperm just jams on through like an arrow going into flesh. Doesn't really work that way!

The only thing I could see impacting anything is if the environment was flooded with a lot of dog semen, which makes the environment mildly more acidic. But that's not really going to be reliable. I literally had a FWB who ended up getting pregnant even while being flooded with doggy spunk every other day.
