In my experience, it depends on the woman. My wife can barely get half of it in her mouth, but she's still very good at it..she practically worships it and loves cum. My ex-wife did fine with the girth, but her jaw would quickly get sore, wasn't very enthusiastic, and didn't like cum....at all. We divorced when she turned out to be gay. I had an girlfriend when I was younger who could handle the entire length and girth easily. Had a ONS with a young woman, back then too, who could not handle it all...she had never been with one as big as mine...sex was difficult and painful, and she had to finish me with a handjob. i havent been with that many women, really, but amongst the few I have had the pleasure of, there was/is a wide range of what they're capable of.
