BDSM seems to have existed as an elite subset of prostitution. Specialty brothels escaped attention. Flagellation was mentioned in Sir John Davies’ Epigrams from 1599, which I haven’t located. Ashbee listed the principal whipping brothels in 1877, located in the better residential neighborhoods.
Swinburne patronized one at 7 Circus Road, St. John’s Wood. “two golden-haired and rouge-cheeked ladies received, in luxuriously furnished rooms, gentlemen whom they consented to chastise for large sums of money.”
Other houses had women whipped by male clients or in front of paying audiences.
In one court case, a 15 year old girl claimed she was beaten, by men known as “Sealskin” or “the Count,” while tied to a step-ladder.
In My Secret Life, Walter describes meeting a girl who describes being flogged by a woman “for a lady’s delecation.” No man present, and the lady was masked.
