So, I am approximately 6.25 by 5.25 - probably average and have been with my wife for several years. I bought an extension a few months ago. It adds about 2 inches and about 1 inch in girth. I've used an 8.25 dildo on my wife before and it seems to be uncomfortable with her, but with the extension, I bottom out. I can push and hit it just as hard as I do without it. When using it the other day with the lights on, the expressions on her face were some that I had never seen before. It seemed like she was almost suprised or something and she came within minutes. I've never really had any issues getting her off. I was just trying to mix it up a bit, but am hoping I haven't turned her into a potential S.Q.. I understand that with women there is quite a bit of emotion/passion and other things involved with sex, but ladies, I'm curious as to if maybe once you have had a large one, that is all you really ever want?
