there is a huge difference between a 7 incher and a 10 incher. Believe me, I know....I've tried, the 7 is a piece of cake {with enough lube} but the 10 incher takes the breath away and it takes a loooooong time to get all that up there. Girth is another matter....Butt, oh baby, when its all there you know it! [and you know it the next couple days as your starfish still itches!]
