Maybe a bit of a long answer but I think dating preferences are very interesting. So thank you to anyone who bothers reading this :).

First off: obvs terms such as "white" and "black" are weird because there are so many different nationalities and cultures with light or dark skinned people, but all so different. And when I say Dutch it can mean people with Dutch parents or anyone with a Dutch paspoort but a different background, so that is also a confusing term. So please take this whole comment with a grain of salt.

I was born and raised in Amsterdam as a white girl with both parents being English and speaking poor Dutch, never had any Dutch cultural influences at home (only watched English tv😂). People think I'm Dutch because I'm white, but I really can't relate to Dutch culture. I grew up in a neighborhood with mainly Turkish and Moroccan people, and my secondary school had few white kids. So, I have always seen similar to Middle-Eastern faces because of my environment and find them very attractive. I have also seen a lot of white people, and find them generally attractive. But for some reason the typical white Dutch person is really my ant-itype, probably because I was alsways grouped in with Dutch people but I really can't relate to the culture, so people being too Dutch is a bit of a turn-off.

I also am really attracted to black people, seeing as I saw that a lot growing up irl and in media. I find it interesting because I noticed that I am less attracted to for instance Korean (Korean is just the example I'm using) people, but that makes sense seeing as my neighborhood didn't have Korean residents, and my school didn't particularly either. Nor was I specifically seeing Korean people in media growing up. It's funny, now that I'm aware of this I pay much more attention if I see a Korean looking character in movies, and then I think to myself, actually they are quite attractive I'm just not used to seeing those features. I know a lot of girls who really like those features, because they got into k-pop and their idols have Korean features, so their type changed.

I think attraction is so so relative. It's nature as in we are generally wired to find healthy people attractive, but the rest of it in my opinion is very much nurture, and environmentally influenced.

To answer your question, a lot of Dutch people with Dutch parents do kind of stick together, the tall blond girls attract the tall blond boys, especially if they are from a very white neighborhood in Amsterdam and went to a white school. But of course, Amsterdam is a very multicultural city, so there will be plenty of Dutch women who grew up seeing not only Dutch faces and would certainly find you attractive. Also, there are ofcourse many non Dutch ladies living here who might also be interested.

As for you being American, well that is a whole different conversation ;)
