I think it's pretty much the same for all races, to degrees. There is a top percentage of men who get to pick and choose which women they want, a large amount of normal guys who have to work really hard to even get a lame long-term-relationship started, and then the bottom percentage who can't get anything. We all believe that. How much does race play into things?
For pure sexlessness we have about 12-14% of black and white men, and over 30% of the "other" races of men. Of course what's most interesting about this chart is that it shows sexlessness skyrocketing for "other" races (and rising substantially for black men). We could speculate that it's because white men are taking ethnic and black girls for themselves (though apparently not the 13% of the sexless white men).
Black men are over twice as likely to marry white women, rather than white men marrying black women. And black men are four times more likely to marry a hispanic woman than vice-versa. White men are way, way more likely to marry asian women than the other way around. (image from

Just talking about men generally there
is this data. It completely confirms what we already knew to be true - some men get lots of sex and lots of partners, others get practically none. With women the averages are more evenly distributed. (this data is allegedly taken from the
National Survey of Family Growth)
Just for shits
this article says approximately 17% of marriages are sexless (for those thinking monogamy guarantees sex). And hey, apparently
the whole country is collectively having less sex than it did 30 years ago.
