I'm personally hoping for exactly 9x7. I know that's still pretty enormous, but my experience with my partner says it should be ok. Worst case is I use some different positions (oh no!). I wouldn't want more than that though. Seems like an anatomical limit. If I get that big and I stretch things out more than I'd like, she's agreed to try kegal weights. But have you seen 10 inches? Having that hanging off your crotch seems like assault with a deadly weapon. 9 is honestly pushing it.
So what's your criteria for, "enough is enough"?
