Regarding the 'Is sugaring prostitution?' debate...
Yes, it is. If the man stopped paying and/or the woman stopped providing sex the relationship
would fall apart in almost every instance.
While it's still under the umbrella of 'prostitution' it is certainly a different ballgame than escorting. There is
usually no fixed time allotted for the dates, and you often do more platonic boyfriend/girlfriend activities than you
ever would with an escort. Still prostitution, though. While the lady might enjoy her time with the SD, her role is still
to be happy around him, ask him questions, etc. It's closer to a real relationship, but it's still not.
A final thought: while most escorts would be very comfortable being a SB, most SB's would never get into escorting
