After simply consummating their business transaction by the completion of the agreed upon contracted services and payment therefore, a client and service provider (匕 so popular in dynastic China) would naturally PART COMPANY, and perhaps use a few hand gestures to wave goodbye, for a time.
Needless to point out perhaps is that a single visit to a professionally trained sexual services provider can sometimes change a person's direction in life, causing a PARTING OF THE WAYS with previous associations. Conversely,「comparing rod head sliding, persons」may initiate a change and SEPARATION of a female seeking a more satisfying mate, or simply be the impetus for extended dildo use.
「Bewitched, charmed, transformed by service provider」perhaps a client becoming enamored with a sex worker and SEPARATING from a mate.「Transformation of, or by, a service provider」「bewitched by a concubine」or,「person」and「comparison, comparative shopping for concubines」will make a decision and then a selection, causing one or more of the slaves offered for sale to PART COMPANY and to become SEPARATED from the others who were not chosen at the same time, perhaps parting from one's close friends formed in friendships while in training for a few months or years, never to be seen again in most cases unless the patron purchased all the slaves available at once, but not very likely. So no matter what else, the one sure thing that occurred every meat market day was that some friends would PART COMPANY and become SEPARATED, END RELATIONSHIPS.

「In traditional Chinese medicine, there has never been a mental disease called pedophilia (or an equivalent term), or homosexuality, or most of the other so-called sexual variations for that matter. …Children are usually described as natural sexual beings and erotic stimulation and sex-play are seen as beneficial to their healthy development.」
