Well I disagree...Every woman would rather take deep fucking then fucking with small dick. It is a fact. But, the fact is also that big dick hurts, so why?
There is not a single vagina in all the world for which you can speak. You have absolutely no first-hand experience with putting anything into your own vagina. Therefore, you are most certainly excluded from being able to speak for womankind. We don't need your help, thanks.
I don't have a dunctuonal size preference. There are things I love about the small dicks I've had inside me, and things I love about the big ones, and all the other ones in between. I'm 100% positive that I can be thrilled by any length between 4" and 11", and any girth between 4" and 7". Almost every human penis is within these parameters. I'd be willing to try outliers, I just don't have high expectations based upon my experiences.
The biggest ones don't have to hurt. When I like for it to hurt, I can arrange myself so that it will. If it hurts and I don't want it to, I can coach a largely endowed partner to give me what I want. Going deep doesn't hurt me most of the time. Going rough, "pounding" hard doesn't hurt most of the time. Any pain I feel comes from too much contact with my cervix. I can teach any willing man to angle away from that, and get even deeper.
When seeking information, it is best, most useful, to lay unsubstantiated biases aside.
