Most women that I have met, civilian or working, don't care what size the cock is unless it causes a problem. The different sizes make for different sensations and bigger is not always better. Size can be an excuse to be turned down for any kind of penetration sex.
The first time anyone mentioned size to me was when I was talking to a certain porn company in Denmark about organising a shoot mainly for my gf at the time although I was going to be the stud, at least to begin with, lol. We are talking 70's here. They wanted a pic of my erection alongside a tape. They said it was better for the picture quality if the cock was more than 18cm (7") they said.
After that I can only remember one other occasion when I was breaking in a girl to the job and while she could swallow me down to the balls, she cant have seen that many cocks as she described mine as enormous which it isnt, but I think she was a bit excited at the time.
Other than that, it has been my stamina that has drawn comment. Over the years one or two girls had clearly had enough well before the end of the allotted time. If you think about it, from a wg perspective she is going to see a full range of sizes but its how long they last that is going to tire the girl out over a day.
