I'm suprised (and a little doubtful) at some of the answers given here, my measurements are 8.75 x 7.5 and I have bedded more than a couple of bus loads of girls over the years so I talk with some experience.
The majority of girls can take me in my entirity, some easily, some where it does cause discomfort because I'm aware I'm very thick but also long enough to go cervix bashing......so I'm suprised the very long amongst us ie 10" plus
can bury themselves ball deep.
Some girls who perhaps have a tender cervix or have never had it touched before freak out and the cry of 'too deep' rings often! I tread gently there, and some girls just physically can't fit me in without it hurting..though I'm aware girth is more responsible for that.
I disagree with some earlier posts, if a girl wants to take you all but is struggling doggy is the worst position to try, it shortens the distance from the vagina to the cervix.....the best position (I'll get stick for this) is straight missionary, but keep those legs flat ladies, the closer the knees get to the ears the less physical space for cock in you.
Ass fucking......with a big cock.....be honest guys, it doesn't really happen does it, girls like the idea but generally once you're head deep they change their minds......look at the size of butt plugs! Bit of a difference. Porn movies have a lot to answer for, those girls take a big salami right up the back hole....or do they?
