It's just such an unenlightened irrational view. If someone wants her vagina stretched to the max there are lots of fun ways to do that, just like if a guy wants his penis sucked as only a shop-vac can do, he has no business expecting a woman's vagina to give the same sensation.
Believe it or not there are plenty of guys who don't get second chances to have sex with women because their penises are too big. Check out the Large Penis Support Group forum (I'm a member of course :) ).
