My ex wife always said mine was "the perfect size". At the time I didn't give it much thought as I thought I was 7 inches due to measuring it one time in my 20's while I was ....... She was a shared wife right from the beginning and with all her encounters she accepted nothing smaller than 6 inches, and I would say her average size was 8 inches. Fast forward 18 years and we are split and I am dating a friend of the ex wife. The first time we get naked she says to me, "(Named of ex wife) said you were 7 inches." I tell her that's right and she points at my cock and says, "That is not 7 inches". So she proceeds to get a ruler and measure me.... 4.5 inches.
That made me rethink the whole thing, cause when I had the wrong size in my head I thought I was right in the middle of the ex's usual cock size range (6-8 inches) of her dates. But now I realize that I was 1.5 inches smaller than her minimum date size and 3.5 inches smaller than her average dates size, plus she had a decent amount of 9's and even one 10 and 12.
So obviously my 4.5 inches was not "the perfect size" as she had said and size mattered quite a bit to her.
