Do you find it offensive?

I think they just meant vaginal depth.

... i think she's referring to the "loose"ness of the vagina?

Even if it's vagina size there are better ways to put it, because even those who use and enjoy bigger toys can enjoy smaller toys. Why not say "those who like bigger toys?"

I didn't think about this in terms of body size either. I can see how you would interpret it that way though, it's a little confusing.

I could see how that might be offensive but it could just be bad wording and the author didn't actually mean "bigger girls" in that sense.
It should probably get edited though since that probably isn't the best way to explain the size of a vibrator in a review.

If it was about weight, it was certainly f*cked up.

I just read it as girls with bigger vaginas

It would depend on the context I would think. If making the assumption that bigger girls all like bigger toys, than yes, that's pretty offensive.

I agree, I would read that as vagina "size" or tightness. It's poorly worded, to be sure. But I hope that this individual is not so deluded or poorly informed to believe that a person's weight has anything to do with what size toys they like. It's more likely, in my opinion, that they just made a bad choice of words. I'm choosing to give them the benefit of the doubt that is the case, but I second the suggestion to message the writer of the review and suggest a word change. If you message them, though, I would recommend doing so with the same benefit of doubt, as in, "This reads like you're saying women who have overall larger bodies or are heavier when I think you mean to say women who have tighter or smaller vaginas."

I've read this in a couple reviews in the past. I usually mention something. I'm never really offended but I figured that it'd be best to let the person know that way they don't end up looking silly.

Either body size or the myth of "tight vs 'loose' vaginas" is ill advised way to talk about people.

Women who enjoy large toys DO NOT have "loose" vaginas!!!! Why is everyone so hung up on body size, this was obviously either a misunderstanding of dildo size preference, or a misunderstanding that only "large" women have "loose vaginas." Both are untrue, as I said before every woman has the sides of her vagina touching while at rest.

There is no such thing as a 'loose vagina." Some women simply prefer large toys or large anything else, and their vaginas spring right back to sides touching when they are don't stay stretched.

Do people who occasionally take a large poop have "permanently stretched" and large anuses?] Of course not. Do people who take large bites of food have "permanently stretched" mouths?

Same thing.
