Britni of Oh My God, That Britni’s Shameless, who blogs about sex toys as well as sexual assault, counseling, feminism, and BDSM, has a PSA about pernicious myths about “stretched out” vaginas.

Attention people (especially guys, because they seem to be guilty of this most often) that are grossed out by women sticking large objects in their vaginas: SHUT THE FUCK UP. Don’t be horrified by the size of the toy and please, don’t make comments about the woman getting “stretched out.” Because guess what? VAGINAS ARE STRETCHY AND ELASTIC. After a fist has been in there, it retracts back to normal very quickly. The same with a toy like Randy. Yes, the vagina will stretch and expand to take the large object. But the elasticity also means that it will shrink back again.

...

[S]he can push a baby out of that thing; a fist is nothing! So you and your penis need to stop with the inferiority complex and marvel at the wonderous things that vaginas can do. ‘Mkay?

She said it here.

Even more eerie? When I did that really massive survey of Tumbler-style porn-photo blogs earlier this year I was reminded again that most people don’t seem get that women’s vulvas change when they’re aroused. Like, a lot. Like that old lyric “lips so sweet and tender / like petals falling apart” vulvas don’t just become “moist,” they engorge with blood — the outer labia push out and open, the inner labia can become almost erect, and the swelling of the clitoral hood led early researchers to mistakenly think the clitoris lost its erection as orgasm approached. If you’re completely clueless about women’s actual bodies, and actual sexuality it might seem alarming; once you figure it out it’s kind of awesome.

A surprisingly common reaction when someone miraculously does appear to be engorged and juicy with her own actual lubrication is that she looks “stretched out.” Hello! You know how people talk about porn giving people the wrong expectations? That’s a really wrong expectation! (As bad as seeing only unaroused penises in porn and then deciding you had to ice them when they got erect because otherwise they looked “wrong.”)

BTW, I’ve got very large hands and yeah, just moments after fifteen minutes of allllmoost (did I mention I have very large hands) fisting someone she squeezed my perfectly-average size hard enough to make me jump. It felt very nice but it was also a very strong squeeze. So yeah, inserting something even very large doesn’t even temporarily “stretch out” anyone’s vagina.
