I’ve read the answers about how and why vaginas do not stretch out from having sex with larger penis’s. I agree that they do not stretch out permanently, but they can for quite a while. I’ve had the unfortunate experience of my wife having a week long, very sexual affair with a much larger man.
I apologize for being graphic, but I’m about average length, and on the low end of the average girth. My wife and I had been married for 13 years, and she had always been very easily orgasmic. Clitoral, PIV and vaginal orgasms. There were times that I could make her orgasm by just giving her a sensual massage. When we were dating, I was the first man to ever make her orgasm - period. She had never even given herself an orgasm.
Well, due to problems in our marriage she ended up having the affair with the much larger man. He was almost 50% thicker, and about 50% longer.
They had sex sometimes 3 times a day for long periods of time. Basically they had sex 10 times in 8 days, and the only reason they missed a few days was because of work commitments.
I suspected an affair, but was in denial at the time. My wife ended up with a very bad UTI from this guy, and we didn’t have sex for two weeks after she last had sex with him. When we did, I couldn’t feel a thing. She was so stretched out it was like the proverbial “tossing a hot-dog down a hallway”. She didn’t have an orgasm with me for almost two months, except for oral.
Prior to the affair I had a hard time getting two fingers in her, afterwards - 4 fingers and I think I could have put my whole fist up there.
Her vagina did eventually go back to “almost” her prior tightness, but it was never as tight as before him. Not a big difference, but it’s noticeable. For her as well.
We’ve spoken of the affair recently and she said she really couldn’t feel me for at least a month after him and that she missed the sensation.
So, do large penis’s stretch out a woman's vagina? Absolutely. Permanently, not likely unless she keeps having sex with the larger man. Most commentators say it goes back right away. I can tell you in my wife’s case it did not. It took a while.
First off, NSFW
I can answer this one fairly first hand. My first wife and I (which will become apparent in a moment why I label her as my First wife) had a cuckold relationship. This means she had lovers and I did not and we both liked it that way.
Her main boyfriend (now her husband) started having regular intercourse and I found out he was almost double my dimensions (I know many will say impossible but later I saw it myself) I'm just under 5″ and he's in the 9 range. As for girth, I’m 5 in diameter and he was about 7.25″ in diameter.
When she started seeing him she would come home after 3 hours of heavy sex with him and and literally couldn't feel me (and I couldn’t feel her). She often complained it was downright painful for the first half hour of having sex with him but also said after she “loosened up” that it was a fantastic “full” feeling.
She felt so loose (but wonderful to me). Think like warm chunky soup, there was something there but zero resistance. However, the next day or a couple days later it would be 100% back to normal giving credit to the theory that it is an elastic that will eventually come back.
As their relationship furthered he eventually moved in and they would have sex 5–6 nights a week. When he would leave for a few days or even a week for work and I once again had access she was completely different down there.
She would tell me that when they first got together it would always take quite a while for her to adjust to him, and slowly it changed and now it no longer was an issue. He just slid right in after a little warming up and it felt amazing right from the start.
They had a break at one point and even after a few months of only sex with me she was still far more loose than before her boyfriend came into our lives. Before they started having sex I could make her orgasm easily with penetration of my penis. After she was used to him, even months after she was last with him, I never witnessed her orgasm again without oral and many fingers. She just said it wasn't enough friction for her to actually “feel” me anymore...
This experience leads me to believe that the vagina was created to fit and enjoy her husbands penis. It is elastic certainly and will go back to “normal” state of you have the odd large toy or encounter but repeatedly stretching the elastic over months or even years will make her vagina have a new “normal” state. This is a good thing, if a woman marries a person who is very well endowed, it shouldn't be painful all her life, her vagina eventually adjusts to accommodate and derive pleasure from him.
What may have been interesting would be whether it would ever go back to it’s smaller state, let's say if you waited over a year or so, but as you can guess I never found out.
Anyways I believe this can also be a warning flag to anyone pursuing a fetish, sometimes when you play with the devil, you get burnt. That was quite a while back but boy writing this makes it easy to see why I'm on to my 2nd (very monogamous) marriage.
Cheers
Update, in the comments section I have put my full story in case anyone is interested. As well I’ve been asked several times if she would say size matters and while I would think it’s obvious from my answer above, yes… she would say size matters… however the guy had insane stamina and I have always had PE. She had said many times it’s more about the stamina than the size…

You should like a decent size, above average. I mean a woman can accomodate a baby head or a finger, they are elastic, what you have to worry about is dating a woman that has several kids through natural child birth, now that’s a helluva girth. I wouldn’t worry about it.
I’ve also been to askmen.com in the past and a sex doctor said that if you stick your finger in a woman for a couple minutes, her vagina walls will tighten to accomodate your finger, then once this happens and you have sex, your penis will feel larger to her, as it got accustomed to the smaller girth of your finger.
Anyway no expert there, but I’ve read some good stuff on askmen.com, no I don’t work for them(lol) but thats a great place to get advice.
As far as comments from guys that have big dicks and are paranoid about dating girls that have had bf’s with even bigger dicks, I’d have to say that I have heard of women like that. They actually go from one guy with a big dick to another, and the guy that has the girl at the time gets paranoid b/c he thinks if another guy comes along with an even bigger dick, she’s dump the guy she’s with to get with this even bigger guy. I can say I’ve never had to worry about that. LMAO!
There was a website out there, can’t remember the name but it referenced Thunders and I found it like 2 years ago. Anyway there was a guy with a large dick that was complaining b/c he was constantly dumped by size queens b/c they were always after the bigger dick. That’s crazy. 8 inches, thats big whether you’ve had 10 or not. I mean damn women’s canals can’t be more than 7.5 inches on average. I wonder how much of the 10” boyfriend hung out of the girl why he was banging her.
Bottom line if you go a dick near 7 inches and at least 5 inches in girth you have a respectable member. Who friggin’ cares if the girls had bigger, she’s with you for a reason. Unless she met you on a nude beach or something.

Wish you all the best
Dear lord…
Ok lets break this down a little shall we…
First off the vagina is like an elastic band. You do know where babies come from right..The vagina is meant to stretch, it’s a muscle. With that said there is definitely and aftercare program you must do after either “play time” or a large penis. Kegals are your best friend!! For a lot of girls that isn’t even needed but everyone is different. Because the vagina is a muscle being stretched out is actually really good for you. Just like everything else use it before you loose it!
Does having sex with men with large penises stretch out the vagina? No. It does not change the shape of the vagina anymore than a large sandwich changes the size of your mouth, or that a large meal changes the size of your anus.
Your question is based on a misunderstanding of the anatomy of the vagina.
When a woman is sexually aroused, blood flows into her genital tissues. This is the same for a man, when he is aroused, his penis and surrounding tissues become engorged (full of blood), we say "he is erect."
Women have the same volume of erectile tissue as men, and engorge just as much. However most female engorgement is inside the body - invisible -and less noticed and less discussed. However, it is just as important for fun as is male engorgement. When a vagina becomes engorged, the walls swell, and the vaginal canal becomes shorter and narrower. As the walls swell, the vagina fills completely with soft, warm, spongy erectile tissue. To repeat, when the vagina is fully engorged, there is no empty space in it (1). Since the engorged vagina is already full, whatever is inserted into it, regardless of size, is completely surrounded - there is no empty space- and the vagina is still completely full So an engorged female can be completely filled by a penis that is one inch/cm long, just as she can be completely filled by an penis that is four inches/cm long. Sensation is transferred through the walls of vagina, regardless of penis size. At some length a penis is, in fact, too long for the vaginal canal and can cause pain. But it does not change the shape of the vagina.

Footnote
(1) If a woman contracts her introitus and tenses up, she can create a hollow or empty space in her vaginal canal, especially if she is not fully engorged. This can happen when doing kegels or by tring to make a “tight pussy” for her partner. If she gently pushes “down and out” - similar to a bowel movement - pushes for a moment and then relaxes, the hollow will fill up.

Hell No,
It is most flexible part you are talking about. Did your mouth become larger when you eat oversize burger or cake? No?
Vagina is similar to penis, when blood starts circulating speedily, it enlarge enough to accommodate penis. Pre-play and arousal is very important as it releases harmons (lube) which make your experience more pleasant.
Very frequent sex might cause little stretch on vagina.
