bonk
I'm reading a book right now called "Bonk: The curious coupling of science and sex" and it discusses the research on cervix dialation during female orgasm. The research showed the the cervix dialated as much as an inch during orgasm with the thought that this was a function of assisting in the passage of sperm to aid in fertility.
So if you have a 1 inch diameter dick I guess that's your best opportunity for cervix penetration.
