1912 Menu From A London Brothel Is Insanely Dirty

The following is a menu of “specialties” available at a London brothel in 1912.

SO MANY QUESTIONS. INCLUDING:
1. “Diddling” with “one foot on the floor” — is it more expensive with both feet on the floor?
2. “Blowing in the ass hole, new style” — WHAT WAS THE OLD STYLE?
3. “…with juice” — ????
4. “10 minutes soak” — soak … in what?
5. “Stink fingers and jerk-off matinees” — oh my oh my.
