Sexual Relationships 
Sexual Health 
I have been a G@G user for almost 3 years(don't ask why I'm xper 1 now)and yes, I've seen countless "Size" questions but one thing I almost never saw is genital size compatibility questions and a lot of people don't know about it so I decided I'm going to help y'all. (Don't ask me how I know this, I learned all of this by googling. Many studies that are posted on the Internet. People just don't bother to look properly. As there are hundreds of them I won't be giving any links)
Penis size and vagina size are like two pieces of a puzzle but it's not that simple. The penis is a hard piece and the vagina is flexible and a stretchy piece
The common thing between a penis and vagina is that they get bigger when the guy/girl is sexually aroused. While the penis takes no time to get bigger and harder, the vagina doesn't become harder. It becomes wet and flexible and takes longer to get fully aroused.
What is a small penis and what is a small vagina?
A small penis is a penis with smaller than average length and girth. Average penis size differs depending on your country but globally it's like 5.5-6 and not sure about girth but in European countries it's around 4.5-5. The definition of a small vagina is a bit more complicated. It doesn't mean a tight vagina. A small vagina is a vagina that has less than average depth and width when fully aroused. But there's a little more you need to know. A vagina is strechy and flexible so a small vagina is compatible with both small penises and medium sized penises because it can stretch to accommodate to a penis larger than itself.Unfortunately there's not been a lot of studies about vagina size so the average vagina size a bit unclear. But it should be the same or a bit smaller than the average penis size in both depth and width when fully aroused(according to the few studies I found online).
What is an average sized penis and an average sized vagina?
From above things should pretty clear already but I'm gonna add that it's the size most people have. Like before, an average sized vagina is compatible with average sized and large penises. Again, because the vagina is flexible and strechy.
What is a big penis and what is a big vagina?
Big means significantly larger than average so no need to explain more. For a big vagina only a big penis will do the job easily.
Now that we are done with size and compatibility I will tell you some facts.
1. For the vagina, streching and expanding is not the same thing. When a girl gets aroused expansion happens and it's called vaginal tenting. It's the same as a penis reaching full erection. Like an average penis becomes 6" long fully erect, the average vagina becomes 6" or bit lesser deep when the girl is fully aroused but now here comes streching. Streching happens by force.(By a baby during childhood and by a larger penis during sex). So by the force of the penetration of a larger penis the vagina can strech( not sure about the limit though) and that's why an average sized vagina is compatible with a large penis. It happens because when the vagina is fully aroused the cervix and uterus lifts up. In the 3rd pic at phase B the pointed area right below the uterus is the strechy place. It can strech but there is a limit. But after sex it returns to it's orginal size. Some of you might be thinking it means big penises are better after reading this part but there's not really a lot of nerves in the end of the vagina and although there are some women who like being streched, there's also women who don't care about it. Even the women who like streching like it have more emotional reasons than physical reasons( for example: thinking that streching will feel good will make it feel good during sex)
2. Regardless of your penis size, you can still please a woman with other things because the 1. the clitoris 2. you can do angling 3. you can her legs closed together to increase sensation 4. the first one third of a vagina has the most nerves so even if she got a 10" vagina an average size can still work. Maybe not as good as a 10 incher but still enough to get the job done.
3. It might look like that large penises have an advantage when it comes to compatibility but then again men don't have to go through childbirth or bear a child for 9 months. And besides size doesn't matter much as long as you can make her orgasm
4. Girth is more important. Girth compatibility is like 100 times more important than length compatibility. A wide vagina will need a wide/girthy penis to feel good during intercourse or piv sex.
5. The loose vagina myth is just a myth. The vagina is elastic.It's impossible for a penis to strech out a vagina. Even after childbirth, a vagina can return to it's orginal size. The pelvic floor muscles may get weak after childbirth but with kegels it's fixable.
We all say size matters but we forget that compatibility matters more. It's time to forget small penis and loose pussy jokes. If you can't feel him/her despite doing all other things then it just means both of you are not physically compatible with each other. No need to shame anyone. You can just move on or try harder.
What Girls & Guys Said
1 1Informative.
Thank you. For some reason I can't see this appearing on the myTake feed. Maybe it's because I'm xper 1 now. Maybe deleting my old account was not a good choice
Haha! It wasn't. What I learned from here is the vagina size matters just as much as the penis. You've done quite a splendid research.
I too had to make a newer account because the 2016 me was immature as fuck. I must say, this one's a lot popular. Almost puts me on the gag map!! Ha.
Yeah. I also found this website at 2016. I used to do xper hunting (posting one word/bad opinions for xper points). I feel like GAG had more people back then. Nowadays I never see funny questions and new users get bored of this site easily.
And this myTake wasn't really that heard. There are many studies posted online , people just don't bother looking for them and spam the same question here everyday. Well maybe I should have waited till I reached xper 5. I really can't find this take on the myTake feed. If I were a new user and suffered from this glitch I'd be super mad.
that hard*
The site has grown upon me as it has on you. Aye?
Yeah. I've been to quora and reddit but this site is always a better q&a site to me. G@G is underrated. It deserves much more.
There are a lot of immature fuckers here, that's why it is so
Strongly agree.
There's a chapter on kamasutra about that
Yeah but they don't explain the streching part and according to them only the same sizes are compatible with eachother and that's not really accurate.
Yeah I agree they don't give numbers like what you've done, but I disagree with last part
There's a table which explains compactibility
which part? the last part of myTake or last part of my previous reply?
Your reply about the same size part
& by the way your take is really good
Thanks..
