Who cares? If a woman is that hung up on the difference, better to find out sooner than later.There have been studies on preference.
Women tend to prefer circumcised penises over uncircumcised penises, according to a recent article, though the authors acknowledged several limitations.www.issm.infoSex and Male Circumcision: Women’s Preferences Across Different Cultures and Countries: A Systematic Review
I have a great idea for you to conduct informal research on preference. The next time you are out socially in mixed company, simply ask all of the women you see what their preference is. Make sure you have pictures loaded on your phone so you can collect informed research. Please report back with responses from your sample and how your research was perceived . LOL
