I found that women and the size of their vagina's vary as much as our penis' do.
A previous relationship I was in, she was 5'1" and took me without so much as a whimper. She was Asian. She never gave me any comments or compliments either.
My girlfriend does pleasantly comment on my cock. She is 5'10" and Swedish. After she and I orgasm and I get hard again, it feels like I can touch her cervix with my cock head. She likes to purr about my thickness and has said it didn't really hurt when I touch her cervix.
So, to reiterate, it is just my observation and opinion that every woman's vagina is different in size that may not be correlated with her physical body size.
And, please, I am not trying to sound like mr all that but I haven't been turned away from a woman on account of my penis size. Women have been annoyed when I can't get it up because I had too much wine or get performance anxiety though. I am not a woman and don't even remotely pretend to know how women think but I hope that when a woman is with me, she is with me and not purely for the size of my cock. Just as I am not with a woman solely because of the size or tightness of her pussy.
