Evolutionary psychology can easily tell you that alpha male gets the women and that he will be muscular, stronger, faster etc compared to other men.

But how does evolutionary psychology explain the love of women for rough sex like slapping, choking, spanking, being tied up, hair pulling etc?

Did whoever who ended up as the alpha male had to force the women into sex? Didn't he automatically get access to the women once he was hailed as the alpha male of the tribe?

How does it even explain choking, spanking, slapping, hair pulling etc? Cuz that would hurt the mother of his to-be-kids
