once you go black you'll never go back 

This statement derives from the general relativity theory published by Albert Einstein in 1915. It refers about the event in which an accelerated body crosses the spacetime boundary of a black hole known as the "event horizon". Beyond this boundary or "point of no return" the gravitational pull becomes so great as to make escape impossible and thus "you'll never go back".

"If a black hole is an oyster then the singularity is the pearl inside. The gravity is so strong it’s always hidden in darkness, beyond the horizon. That’s why we call it a black hole, once you go black you'll never go back."

Once you've had white, you never go back to black.

A phrase that primarily applies to black women but is also applying more and more to black men in America. Single black women having become disillusioned with being the breadwinner and homemaker of the family. In dating white men, black women have discovered that white men tend to be more financially stable, less likely to cheat, less likely to be abusive, and if there is a pregnancy are more likely to stick around and be a part of the child's life even if the relationship doesn't work out. All things that women want in a relationship.

Once you go black, you never go back 

Vulgar idiom with American origin is typically used to imply that sexual activity with an African American or a black person is so enjoyable that one will exclusively seek out black partners in the future because of that.

Likely to harken back from taboos surrounding African Americans during the Antebellum period in United States history. During this period, large amounts of stereotypes existed around African Americans, many, also sexual. Racist ideas were held like that black men were considered to be animalistic and unable to control their sexual urges, which made having a romantic relationship with a black man, especially as a white woman, extremely taboo. All southern states had anti-miscegenation (anti-interracial marriage) laws, which weren’t abolished until June 12, 1967, by Federal law.

Many kinks surrounding black men specifically, like many kinks, are rooted in older taboos, which are now gone.

“Ava said that since her last boyfriend, she has had an amazing sex life.”
“Well you know what they say.”
“Yeah, 'Once you go black, you never go back'.”

Once you go black, you never go back 

Once a woman sleeps with a black man, no white man will be able to satisfy her, so she sleeps only with black men from then on. Usually because of their girth and size, but also because they appreciate more types of women in general and have better moves.

After she'd been with two black guys, she realized that once you go black, you never go back, because size really does matter.
