Does a Thick Penis Make a Vagina Looser?

A pejorative that some people call women who they think are promiscuous, is loose. The idea behind that is a vagina that is stretched over and over from intercourse would show sign of use. What is never considered is a married woman who has regular sex rarely gets called loose. What these men (and some women) fail to realize is the vagina and pelvic floor are designed to expand. The muscles can stretch and there are folds in the vagina (called rugae) that unfold and allow for stretching that happens during intercourse and childbirth.

Vaginal Tightness

Just as there are varying sizes of penile length and girth, there are also varying sizes of vaginal length and diameters. The vagina is considered a potential space – meaning that when it is not aroused, the vaginal walls are typically touching. When aroused, the vagina fills with more blood, the rugae relax, and the vagina secretes arousal fluid; allowing for a comfortable expansion that accompanies intercourse. Even though the vagina can expand, there are limits to what is comfortable. What typically causes issue for the vagina being overly stretched is not the vagina itself, but the pelvic floor that surrounds it. To illustrate an analogy:

Imagine a hand towel stuffed inside a thick sock squeezed by two hands. The sock is the vagina. The towel is the folded muscle tissue of the vaginal wall. And the hands are the pelvic floor muscles that surround the vagina.

The Rare Truth About “Tight” and “Loose” Women

The hands in that analogy are what is keeping the vagina tight, and if those hands grow weak, they do not squeeze as hard. The result of that is less resistance when attempting to stretch – which makes the vagina feel looser.

Vaginal Looseness

Vaginal looseness (or medically – vaginal laxity) can happen during childbirth. There can be tearing of the vaginal skin and vaginal opening, but those typically heal on their own, or in extreme cases, may require surgery. But some couples have reported that there is a loss of sensation during sex after childbirth. The perineal lacerations (tears during childbirth) may have healed, but there is still an issue even months after giving birth. That loss of sensation is due to the pelvic floor muscles. A baby’s head averages 13 inches in circumference. The vagina (and pelvic floor) is amazing thing, and many times even after expanding large enough to pass through what no penis girth could ever match, can return to the near identical tightness it was prior to childbirth. The determining factors of vaginal tightness after childbirth have to do with the vagina size, baby size, genetics, previous childbirths, and even kegel exercises.

What about a Thick Penis?

The thickest penis in the world is not 13 inches in circumference – not even close. However, there are some that can get up to over 7″ in circumference. A penis of 7″ inch circumference is extremely rare, but does exist, and a question may be will a vagina that has expanded enough to have intercourse with 6″ or 7″ around penis shown sign of use?. Well, what do the experts say?:

Dr. Sherry A. Ross, MD, ob-gyn at Providence Saint John’s Health Center in Southern California and author of She-ology, says a well-endowed partner can also make things looser—but only at the vaginal opening, not throughout the vagina itself. But even that loosening isn’t all that substantial or noticeable. “Your vagina accommodates a penis fairly well,” says Dr. Ross. “I mean to really stretch out the vagina, you need a baby coming through it.”

Relax! The female body is designed to adjust to be elastic and expand to accommodate everything from a large penis to childbirth, says Streicher. “Even the largest penis in the world won’t compare to the size of the baby, so it won’t affect the size of the vagina.”

Reddit Asked: Can Sex Affect the Size of Your Vagina?

See my mechanistic explanation in the following blog I wrote:  https://healthdoc13.wordpress.com/2018/02/24/when-sex-hurts-and-pain-replaces-pleasure/Huge thrusting into petite x many hours cumulatively = some degree of stretching and loss of tone

Email correspondence I had with Dr. Andrew Siegel

So three different doctors were asked. One stated just the vaginal opening can be loosened, another states no loosening at all, and the last states the vagina will be loosened if the vagina is very small and the penis very thick. So who is correct?

Did Your Ex Ruin It?

As mentioned in the first paragraph of this post, calling a woman loose is usually perceived as an insult. We can completely dismiss a promiscuous woman feeling looser because she has had a very active sex life. But how about if one of her partners had a very thick penis? What if what was once painful, now feels good? The vagina is now accommodating the larger partner, but what if that relationship ends? Will going to back to an average sized penis not feel as good – for him or for her?

How can all three experts say different things, but they all be right? Let’s examine:

  • Dr. Sherry Ross stated that the vaginal opening can be loosened, but to the point that is not even noticeable, so that point is really moot.
  • Dr. Lauren Streicher stated that it will not be loosened. What Dr. Streicher didn’t really mention is the average vagina will not be loosened. The average vagina can stretch enough to accommodate a very thick penis. When sweeping medical advice is given, it might be excluding outliers.
  • Dr. Andrew Siegel goes into a little more detail. When asked about it, he said that a thick penis can stretch a vagina, but that it would have to be the extremes.

What is missing is an important question. Is it permanent? The answer is no. If a woman has had slight stretching from regular sex with a very thick penis, and she is no longer accommodating a large object; her vagina will tighten back up. Dr. Siegel is a big proponent of kegel exerises for women post childbirth, so even if she has damage to her pelvic floor from a 13″ around baby head, it can be treated. However, no penis is large enough to match that kind of damage done to the pelvic floor.

Does a Thick Penis Make a Vagina Looser?

So, does a thick penis make a vagina looser? Yes. The vagina is designed to be accommodating. Is the loosening permanent? No. So if you ever read or hear some story about loose women, don’t believe it. The loosening isn’t permanent and for most people, not even noticeable. I will close this post with a quote from Dr. Sherry Ross:

What about all the jokes guys make about having sex with a woman who is loose down below? Don’t believe them—it’s unlikely that a man can really notice the difference. “I think guys can tell when a woman is a virgin, and they can probably tell if someone’s had two babies or have had a vaginal birth,” says Dr. Ross. “But I don’t think they’re really going to notice much of a difference . . . unless a guy has a really small penis.”
