wife has measured me a couple times. the first time, she and her gfs were comparing their mates cock size. it was their girl nite out topic apparently. she measured me, wrote it down, didn't comment. later, when she came home. she woke me with a BJ then rode me til she came. afterwards, she told me "she won" or rather "I won". I had the biggest cock out of the group. she said something like, "I told you you had a big dick.".
the other time, she and the gfs had found some size chart on the internet or from it, and she was curious were I was on the chart. she came home again, woke me with a BJ, riding me hard. told me I won and that I was "a rare man". less than 1 in 100 men were my size, blah, blah. she said of the other gals were jealous and some asked her if I could fuck them. she told them no. turns out she was the only gal that was not sexually frustrated, and that was true because back then, we fucked at least once a day. she had orgasm(s) daily and some of these gals couldn't remember the last time they had one.
