My wife has been consistent over the years - her view is that 7-8" is perfect (for her), 6" will do (I'm about 5.5). Larger than 8 and she insists on "special positions" to avoid discomfort. She will ask him to "ride her high" while in missionary so that he can't get the full length in because in her words "it doesn't feel good banging against her cervix." The sex turns to work to accomodate and that's not why she's in our bed with him. My wife wouldn't just say "put that away" (it's a great question, by the way!), having brought a personable, attractive well-hung male into our bedroom or her hotel room, she'd still want to undress him, make out with him, and otherwise enjoy every aspect of him, but she'd finish him with one of her fantastic knob jobs. He wouldn't leave unsatisfied. Then, it's my time.......
