I guess I’m similar to several guys on this thread. I am currently just a bit over 8” by 5.8” girth, and I have a couple “variations” on my dream size. If it was a size I would be forever and that my wife would have to learn to accommodate and hopefully enjoy I would say 9.5”x6.5”. If it was just for “fantasy” or just for me to enjoy handling and jacking off I would go really huge… like 10”x 7.5” - which would be insane and my wife would likely not appreciate!
