Let's not be bitter. At least not too bitter...
There are, in fact, women who are size queens. As far as I've been able to tell, they're the definite minority.
It's been pretty obvious that the whole size thing is all male oneupmanship.
Hell - some of the ads say things like "she complains that sex hurts now" or "she gags during oral." This is supposed to be a good thing?
What I remember from Asia Carrera's blog was something on the order of "you can reach my g-spot with your fingers, so it doesn't need to be much longer than that." She also had a maximum length she would work with - I can't remember if it was 7 or 8 inches.
In the meantime, if I really, really suddenly feel the need for a bigger dick, I'll do the one thing that works - which I should be doing anyway - and lose some weight.
