My guess is that a vast majority of women really don't care about size but I think there is generally a limit. My wife is DEFINITELY not a size queen. She has mentioned that she thinks I have a large dick, but it was never a compliment, more of just stating a fact. If anything, she has wished I were smaller. However, I was REALLY surprised when she told me that she does have a limit on how small she'd be interested in. I don't remember if she gave an actual size but she did have a limit. I also am sure there is an upper limit and based on what she's said I probably exceed it. She knew how big I was when we got married and her solution is apparently to avoid intercourse at all cost. I got the impression that if the guy was too small she might literally stop dating him.
So why did she not dump me if my size wasn't conducive? First of all, she was a virgin when we married so maybe it was a bit more difficult than expected. Second, I wonder if there is a psychological effect. I wonder if being married to a husband with a too large dick is psychologically very different from too small. Both might make intercourse less pleasurable but perhaps one makes you feel less of your husband. My wife is very reticent to talk about this stuff so I don't really know what her thinking is.
