I'm 7 and fairly thick. My wife is always telling me how perfectly she thinks we fit together, and we have a wonderful sex life together. My 7 is much more comfortable for her when it comes to oral, anal, or the hard pounding she likes at times. But on occasion she gets an itch that I can't scratch and we invite one of our larger 9-9.5 friends over for some play. I think very large cocks are great but not sure I'd trade mine in!!
