The fisting forums are great. There are women and men there discussing vagina enlargement, much the way we practically and clinically discuss penis enlargement. And they have more or less answered “how big is too big” once and for all. There’s almost no such thing as too big.
Seeing the same topics from a completely different point of view has elucidated the topic of too big. They talk about size in terms of width, circumference, and depth. They stretch their vaginas with dildos, and know exactly how much width and depth they can take. Although most of them only care about width, some of them do stretch for depth.
First revelation I read was that for the most part, they cannot change their vaginal depth. No matter how they try, it does not change by more than 0.5” and is limited by the distance from the vulva to the spine. Almost all the women had depths of 6” to 7.5”. This confirms what we know about length. 6 to 7.5 NBP is what most women can take, and then it’s bottoming out. There are deeper women, but they are rare.
Then there’s girth. There is basically no limit on width and circumference, they just keep stretching over time. Any woman can do it, and they get into it in various ways. A 7” circumference dildo is beginner’s territory, 8” and 9” are intermediate, and 10”+ is advanced. Some can double fist even more, basically the entire birth canal because it’s only that thick at one point.
Women who stick to single fisting only, or about 8-9” for dildo girth, report that their pussies go back to completely normal if they stop. Beyond that, there is permanent stretching. And I got the sense that getting up to 7”EG would be very easy for any woman if she really wanted to do so to accommodate a partner’s large penis. And fun fact, women who stretch their vaginas out do not experience vaginal tearing from child birth.
This is all great motivation, and provides such clarity on the nagging question how big is too big. There’s the joy of discovering PE, and then the anxiety of choosing when to stop. Hoping one won’t regret too much of a good thing. And now finally clarity. No practical benefit to going beyond 7.5 NBP unless with a specific girl who is known to be longer. And for girth, the sky is the limit, well 8” or 9” is more like the limit but that is a lifetime of PE. So there is the answer to the question. PE for girth for life, and fear no consequences, any new partner can get accustomed to it, and any long term partner will adjust to gains over time. PE for length into the 6-7.5 NBP range and be ready to bottom out beyond that.
