Curious if anyone male or female a race fetish? Meaning they are only or primary attracted to a specific race.
I was checking out a OF of a companion on here which lead me to a few rabbit holes.
by Observation their seems to be be a 'fetish' with black males. Specifically White woman fetishizing Black males.
In addition the husbands of white / asian woman fetishing black males being with their partners.

Race play

I could not wait to see women of different colors, nationalities, etc.   Even seeing heavily inked gals is a turn on.

tho I never limit myself to only Asian women. There is beauty in all women and I take them on a case-by-case basis.

My entire life I have always been attracted to White Guys, Spanish Guys and Black Guys

Quite a few males are attracted to asian features.  
.
OnlyFans might be more guided by what brings in the fan dollars -- which might mean specialization.
.
On FetLife the majority is submissive white females. Hot wife is a big category -- cuck men.  Black men on white women, the women tend to be "bigger".
.
These are my observations -- not scientific statistics.

I strongly believe there is a vast spectrum of fetishes, kinks and just plain desires out there.  Masters and Johnson and others after them have documented what a wild and varied species we are when it comes to sexual wants.  Porn sites have long included the "blacked" and "black cuckold" fetishes. I'm not sure how much those sites tell us about what is an actual trend in the larger population, but their popularity may be some indication.
Having said that, when I ventured out into the dating world after my divorce, I encountered more than one white woman who thought that because I'm a black man I must be packing 10-inches of steel pipe in my boxers, and can fuck all night every night. Sorry to disappoint ladies; I'm pretty average.  
So I'm careful about buying into stereotypes--the hypersexualized black man or woman, the demure and servile Asian woman, the hot-blooded Latina, the domineering Teuton, you name it.
Having said that, if an adult's fantasy is a well-endowed black man, a bosomy Swedish gal, a Japanese lady in traditional dress, or a left-handed redheaded tattooed small person with a lisp, I say Rock On.

Lots of prior posts about beauty and perception. Here's one:

"... Studies of beauty as perceived in ethnic faces have been conducted, as well, and not by comparing pictures of top models (Nyong - Banks) but by computerized blending of face photos of different types.  SYMMETRY is one of the more important factors in determining a test subject's assessment of beauty.  Asian female faces are at the top and I think it had something to do with the angle of the eyes emphasizing the symmetry.  This  - - kind of looks like a line with a space somewhere in the middle, maybe, but \ / zooms in at the centerline and enhances is (symmetry). ..."  

I prefer American white women - preferably from the Midwest..  

Age?

I have ALWAYS had an attraction to Latina women for as far back as I can remember. I love their ability to be so affectionate i love their ethnic features which are so beautiful, and their body type is just right to me more than any other woman. Not to say another ethnicity couldn't have the same features. I'd probably be attracted to them as well in that case. Contrary to popularity here, I'm not attracted to Asian women really. Which in all reality is the exact opposite in most cases than Latina ladies.  
I probably haven't made an appointment with an Asian provider in 10+ years. Latina.... now, that was just last week!! 😃

I would say 25-35 would be my sweet spot..   Petite.  Under 5'5" and no baby damage.  Non smoker.

I have been giving this some thought as I have definite preferences when it comes to women. I’ve long noted that I’m not especially attracted sexually to Asian women.  Not to say they aren’t beautiful, for example the geisha look is stunning, but doesn’t really turn me on.  
In this case I believe it’s actually a question of body type. I adore women with soft curvier bodies, a nice rounded butt, soft supple pillowy breasts, even a little roundness in the face, not overweight, but feminine.  I love all types of women, but that body shape is my favorite.  

Asian women seem to be more on the thin/small side not quite as "curvy". Still very pretty for sure. Just not my preference.
Latina women just seem to be much more on the sensual side and very "curvy" which IS my style.

Costa Rica is a magnet for Latinas from all over and there's a wide range of looks. Even Ticas (girls from Costa Rica itself) don't all look alike. Some are lighter, some are darker. Nicaraguans usually have darker skin. Colombianas are very European looking, with elegant, chiseled features. Especially those from Medellin.  Girls from the DR are more classic Hispanic looking. Cubanas come in all colors. I was with one a few years ago who was a classic little spinner.
Whatever over-simplifications are being shared here, Hispanics are a mixture of Spanish, Black and Central American Indian blood. How much of each an individual girl is made up of has everything to do with how she actually looks.

I've seen plenty of Thai women who are curvy and Thai and Korean women are are amazingly sensual.

Lol... That can be said for all ethnic groups and races. There's lots of variety in every culture. My statement was more in general than anything.
Speaking of Costa Rica. I absolutely love the women native to CR.They are so beautiful and friendly. The last 2 times I went to Costa Rica I chose to stay out of the Cocal. It's like shooting fish in a barrel at that place. The last times I went it looked like a retirement convention was going out there.🤣
Instead, I chose to go to more of a local scene where I figured I'd find Ticas local to the area.
And sure enough, I met the most beautiful Costa Rican lady. In a coffee shop of all places. We had a GREAT weekend! Absolutely stunning and so friendly. I almost couldn't believe my eyes. I love the accent although she says she likes mine ...haha. We still stay in contact today!

1000% for Korean woman ..  they can be tall curvy (typically with help) and hella sexy

Agreed,, but is it a fitness thing or a big D thing or a taboo thing.. is what I wonder.

And it was kinda dead. I haven't actually stayed there since around 2016 because I'd rent a nice condo up the beach for a couple of months and swing by the Cocal in the evening to sample the buffet. The real loss is the closing of the Del Rey in San Jose. That place was like The Titty Twister in "From Dusk 'Til Dawn" but without vampires.

I felt like the Del Ray was a bit of a dump. Locals ticas will show you the real good places to be. Guess I lucked out at the coffee shop!

But to me that was part of its sleazy charm. I stayed there a few times but finally got grossed out by the dingy, noisy rooms. I started staying at the Sleep Inn just up the street by the Parque Morazon, which was much nicer.
The other option was the Sportsman's Lodge just across the Morazon.
