Only those who have fucked all four should answer the question and I suspect that ain't most of those voting.
Asian chicks (my experience; Cambodian, Filipino, Thai) as a group has the wettest pussy
Skin color has nothing to do with how wet a woman's pussy gets. It's about the woman and the chemistry between that woman and you. Now there are some women that'll get soaking wet but skin color is not a factor, it's about that woman.
at cats actually coming in here to answer this stupid ass question.
Need Asian to properly compare. However had Mexican once that was juicer than 2 tangerines.
