The image of the cruel white slave master and his sons having their way with the female slaves was nowhere near 100% true. Look up hypergamy and the desire of females to marry up. And reproduce upwards too. Such as a female slave will want lighter children (more status and better chance at education etc.) so makes some babies with the slave owning family men.
1000x more taboo was the male slave having relations with females in the slave owners extended family
interesting - I spent some time in the Caribbean islands 60’s and 70’s and a put down was when on native said to another “you black,” meaning he had darker skin therefore was inferior in some way.
A number of years ago some college professor in the US lost his job when he published a paper which claimed, in part, that the Caribbean blacks were physically the better slaves in some way (can’t recall the thesis). Down there they will tell you it is true. The slave ships which had money to purchase supplies, instead would sell their human cargo down island to buy supplies and pocket the supply money telling the owner the slaves died in route and thrown overboard. The island plantation owner would choose the men with the best physiques for working and the women who would be the best producers - large hips and breasts) (as you would buy cattle). Until the missionaries arrived the slaves were not allowed to marry. The cargo remaining was sold in Georgia and South Carolina. So I was told several times by native island bar tenders. I was not a tourist while down there.
