As a guy of Indian descent, here is what I can say about my experience with women.
American girls from smaller towns and more "conservative" areas have been by far the nicest to me. This is in huge huge contrast to American women from big coastal cities. My worst experiences have been with women from The Bay Area but I hear that is because Indians have a really bad reputation there compared to the rest of America. My best experiences have been with white women from places like Minnesota, Wisconsin, Florida, South Carolina, Tennessee, Indiana, Mississippi (yeah Mississippi lol!), New England states that are not Massachusetts, and Ohio.
Once again, the small town girl types are super nice to me and fall hard for me.
I have a really good experience with African American women too.
With Euro women, I have a great experience with the vast majority of them except for women from Spain and Italy. Spanish women are the worst by far without any question. I used to love them a lot since I am a sucker for the tanned brunette look but thank god for creating the Balkans and Romania!
With Latinas, my best experiences have come from Mexican women but all other Latinas are cold AF to me. I struggle mightily with Colombian women and have had an awful experience with Puerto Rican women.
With Middle Eastern and Arab women, usually North African and Israeli girls are chill with me.
Thankfully though, I still got Indian girls in my corner. What I love is how I have that option available, if you are a cool Indian dude they go hard for ya.
Worst experiences have been from Latinas that are not Brazilian or Mexican.
